Difference Between Electrical and Electronic Devices

The major difference between the electrical and electronic devices is that the electrical devices convert the electrical energy into the other form of energy like heat, light, sound, etc. whereas the electronic device controls the flow of electrons for performing the particular task. The other differences between the electrical and electrical devices are illustrated below in the comparison chart.

The electrical and electrons both are interrelated with each other. The electrical is the flow of electrons, and the electronics is the technique of controlling the flow of electrons for doing the particular work. The working principle of both of them are same, i.e., uses the electrical energy for doing work.

Key Differences Between Electrical and Electronics Devices

The following are the key differences between the electrical and electronic devices.

  1. The electrical device changes the current into another form of energy like heat, light, etc. whereas the electronic device controls the movement of electrons for performing the operation.
  2. The electrical devices use copper and aluminium wires for the flow of electrical current whereas the electronics devices use the semiconductor material.
  3. The electrical devices mainly work on the alternating current whereas the electronics device works on the direct current.
  4. The electrical devices work on high voltages whereas the electronics devices work on low voltages.
  5. The power consumption of the electrical devices is more as compared to the electronics devices.
  6. The conductivity of the electrical devices is high whereas it is low for electronics devices.
  7. The electrical devices do not manipulate the data whereas the electronic devices manipulate the data.
  8. The electrical device directly works on the current due to which it gives the quick response.The electrons are the only moving charge of the electronic device and hence their response time is less.
  9. The electrical device is heavy and larger in size and hence requires more space whereas the electronics components are very smaller and placed on the single chip or we can say it requires very less space.
  10. The electrical device is more dangerous as compared to the electronic device because in electric devices heavy short circuit occurs because of the fault which is very dangerous for life.
  11. The fan, transformer, motor, generators are the examples of the electrical device whereas the transistor, thyristor, microcontroller are the examples of the electronics device.


The electrical and electronic devices both depend on the flow of electrons for performing the operation. Both the devices use the transformer for transmitting the voltages. The electrical devices use both instrumental, and power transformer and the electronic devices only use the instrumental transformer.
