Question

Electric Current is rate of change in a) Electric Potential b) Electric Charge c) Electric field d) Induction​

Answer 1

Answer:

electric current

Explanation:

The rate of flow of electric charge is known as electric current. Electric current is expressed by the rate of flow of electric charges . SI unit of electric charge is coulomb

Answer 2

Electric Current is the rate of change of ELECTRIC CHARGE.

But why?

• Charge is a physical property of a substance which helps it to experience a force when kept in an electromagnetic field.

• Now, when this charge flows, we say that a current is present.

• So, current is essentially the rate of flow of charge. Mathematically, what is defined as the rate of change of charge with respect to time.

• SI unit of current is Amperes (C/sec).

$\boxed{i = \dfrac{dQ}{dt} }$
