Question

What does a electric circuit mean? state in brief the meaning of variable resistance
pri) Calculate the number elections Constituting
One Coulomb of charge.​

Answer 1

Answer:

1. The electric circuit is the continuous path which allows electric current or electrons to flow through it. An electric circuit consists of connecting wires, other elements
2. It is an electronic component. It is applied in an electronic circuit for adjusting circuit resistance to control voltage or current of that circuit or part of that circuit. The electrical resistance is varied by sliding a wiper contact along a resistance track
3. One electron possesses a charge of 1.6 ×10-19C, i.e., 1.6 ×10-19C of charge is contained in 1 electron. Therefore, 6 x 1018 electrons constitute one coulomb of charge.
