Question

How do you define electric current, conventional current and electronic current?

Answer 1

Electric current,

1. Current is the rate of flow of charge.
2. If a charge '$q$‘ flows across any cross-section in ’$t$‘ second, current ’$i$' is given by, $i=\frac{q}{t}$
3. The unit of current is ampere, which is equivalent to coulomb per second.

Conventional current:

1. The conventional current is due to the flow of positive charges or holes from the positive terminal to the negative terminal.

Electronic current:

1. The electronic current which is due to the flow of electrons from the negative terminal to the positive terminal.
