Q1:

In a two-source circuit, one source acting alone produces 12 mA through a given branch. The other source acting alone produces 10 mA in the opposite direction through the same branch. The actual current through the branch is

A 22 mA

B 12 mA

C 10 mA

D 2 mA

ANS:D - 2 mA

Opposite direction current subtraction.
