Parallel Circuits - Engineering

Q1:

The following currents are measured in the same direction in a three-branch parallel circuit: 200 mA, 340 mA, and 700 mA. The value of the current into the junction of these branches is

A 200 mA

B 540 mA

C 1.24 A

D 900 mA

ANS:C - 1.24 A

At the junction , by kirchoffs ct law,
200+340+700=i;

So i=1240 ma or 1.24 amps.
