Correct Answer - Option 2 : 4 A

Concept:

Electric charge(q): The property of matter which is responsible for electrostatic force is called an electric charge.

The SI unit of charge is coulomb (C).

The rate of flow of electric charge is called an electric current.

\(Electric\;current\;\left( I \right) = \frac{{charge\;\left( q \right)}}{{Time\;\left( t \right)}}\)

Charge (q) = current (I) × time (t)

Calculation:

Given that;

Charge (q) = 100 coulomb

Time (t) = 25 sec 

\(Electric\;current\;\left( I \right) = \frac{{charge\;\left( q \right)}}{{Time\;\left( t \right)}}\)

\(I=\frac{100}{25}=4 \ A\)
