Circuit Theorems in AC Analysis - Engineering

Q1:

If two currents are in the same direction at any instant of time in a given branch of a circuit, the net current at that instant

A is zero

B is the sum of the two currents

C is the difference between the two currents

D cannot be determined

ANS:B - is the sum of the two currents

When two currents are same direction addition will will takes place. If in opposite direction subtraction takes place.
