RL Circuits - Technical MCQs

Q1:

In the given circuit, IT equals _____.

A 0.5 A

B 2 A

C 1.5 A

D 2.5 A

ANS:D - 2.5 A

You are is correct @Rathi.

Explanation is due to the current flowing in R and L have 90-degree phase different the total current cannot be plus.

So, I(T) = sqr(I(L)^2 + I(R)^2).
