Principal Differences Between Electronic And Electrical Devices

electronic and electrical devices

Electrical and electronic engineering might appear to have the same thing, yet they are not. The similarities end there. Both require transporting energy around a circuit to power valuable items and devices.

Electrons and electricity are inextricably linked. The passage of electrons is what electrical is. Electronics, on the other hand, is the method of directing the flow of electrons in order to do a specific task. Both employ electrical energy to do work, which is the same operating principle.

The majority of modern appliances make use of a combination of electronic and electrical circuits. An electrical circuit in a washing machine includes a plug socket, fuse, on/off switch, heater, and motor that rotates the drum. The user enters the appropriate washing process and temperature via the control panel.

Key differences and types of electronics and electrical devices

1) Electrical devices

Electrical devices are those that transform electricity into different forms of energy or work. It conducts electricity using metal. The majority of electrical gadgets operate on strong alternating currents. Electrical equipment also consumes a lot of power.

Electrical equipment is more unsafe and less dependable since they cause dangerous electrical shock. The size of electrical gadgets is very huge, necessitating additional space. A fan, for example, is an electrical device that converts electrical current into rotational motions. The electric bulb, lamp, or tube light transforms current into light.

2) Electronic devices

Electronic devices are devices that control the flow of electrons for the purpose of accomplishing a specific activity. The term electronics refers to the study of electron activity in the direction of the electric field.

There are two basic components of electronic devices, i.e. active component and passive component. The component that delivers energy is referred to as the active component, while the devices that receive energy are referred to as the passive component.

The electronics consist of three major active components and two major passive components. The active components include resistors, capacitors, and inductors, whereas the passive components are tube devices and semiconductors.

Key differences between electrical and electronic devices

Despite this, both electrical and electronic devices rely on the passage of electrons to execute their functions. However, there are some differences between electronic and electrical equipment.

  • For the flow of electrical current, electrical devices utilize copper and aluminum wires, whereas electronics devices use semiconductor material.
  • Electrical devices mostly operate on alternating current, whereas electronics equipment runs on direct current.
  • Electrical devices operate on high voltages, whereas electronic devices operate on low voltages.
  • The power usage of electrical equipment is higher than that of electronic gadgets.
  • Electrical devices have high conductivity, whereas electronic devices have low conductivity.
  • The electrical device operates solely on current, resulting in a rapid response. Because electrons are the electronic device’s only moving charge, their response time is short.

Types of electronic devices

Basic Electronic Components are electronic devices or pieces. They are often packaged in a discrete shape with two or more connecting lines or metallic pads. Some of them are as follows;

a) Resistors

A resistor is a type of electrical device that resists the flow of electrical current. It is a passive component that enables resistance to control or obstruct the flow of electric current in an electric circuit. As a result, there is a voltage drop across the circuit.

There are a variety of ways of constructing a resistor. Some are little more than a coil of wire constructed of poor conductor material. The most popular and least priced consists of powdered carbon and a glue-like binder.

b) Capacitors

A capacitor is a device that accumulates and emits electricity, usually through a chemical process. A storage cell, secondary cell, condenser, or compressor are all terms for the same thing. A capacitor in the form of a Leyden Jar was an early version. Capacitors are split into two contacting areas separated by an insulator, each with a wire lead connected to it.

c) Inductors

An inductor is a passive electronic component (usually a conducting coil) that introduces inductance into an electric circuit. It is essentially a coil of wire with numerous windings, often wound around a core consisting of a magnetic substance, such as iron. A coil of wire is the most basic form of an inductor. The third and last sort of basic electronic component is the inductor.

Types of electrical devices

Electricians utilize a variety of tools in their job, many of which were described previously. Electricians face a variety of hazards while performing their duties. One method to mitigate these dangers is to understand the purpose of each instrument and be aware of the options available to them to protect themselves. There are a number of electrical items or components in every house.

a) Transformer

A transformer is a passive electrical device that uses electromagnetic induction to transmit power from one circuit to another. Its most typically utilized to raise (‘step up’) or lower (‘step down’) voltage levels between circuits.

A step-up transformer is a transformer that increases the voltage between the primary and secondary windings. A step-down transformer, on the other hand, is one that reduces voltage between the primary and secondary windings.

b) Generators

Generators are helpful gadgets that provide electricity during a power outage, preventing the disturbance of daily routines or commercial operations. This equipment comes in a variety of electrical and physical designs for usage in a variety of applications.

It is critical to recognize that a generator does not ‘produce’ electrical energy. Rather it uses the mechanical energy provided to it to accelerate the passage of electric charges present in its windings’ wires through an external circuit element. The flow of electric charges represents the generator’s output electric current.

c) Motors

An electric motor’s goal is to transform electrical energy into mechanical energy. This mechanical energy can then be used to power everything from big industrial machines to common household items like hair dryers.

Every motor has two critical components: the field winding and the armature winding. The primary function of the field winding is to generate the static magnetic field, whereas the armature winding appears to become a conductor organized within the magnetic field.


To conclude, the main theme of this topic is to highlight the difference and types of electrical and electronic equipment. Electrical devices use electrical energy for conducting tasks. However, electronic equipment controls the flow of electrons for performing a specific task. 

There are different types of electronics and electrical devices. Inductors, resistors, capacitors are examples of electronic components. On the other hand, electric motors, lights, and transformers are some common types of electrical gadgets.

In this major industry, the role of expert technician or electrician is highly important. As they know the basics and background of the field like how to repair, install or measure the electric current. For example, if your AC unit becomes useless, firstly, you call your electrician for the service of repairing an air conditioner. So this article is appropriate for understanding the difference between electrical and electronic items.
