What is the effective value of current?

(a) RMS current

(b) Average current

(c) Instantaneous current

The correct answer is (a) RMS current

Explanation: RMS current is also known as the effective current. RMS stands for Root Mean Square. This value of current is obtained by squaring all the current values, finding the average and then finding the square root.
