Parallel RC Circuit

Answer: A. 5 mA

In a parallel RC circuit, 3mA through the resistive branch and 4mA through the capacitive branch. The total RMS value of the current is 5 mA.

Solution:

Given that in the parallel RC circuit, 

current through the resistive branch = 3 mA

current through the capacitive branch = 4 mA

therefore, the total RMS current is = √(3²+4²)=5 mA

Hence, option A is the correct answer.
