In the circuit shown below, the current in the 2 ohm resistor is 2 A. What is the current in the 3 ohm resistor?
A) 2 A
B) 3 A
C) 4 A
D) 6 A
Seeing that the answers were all nice numbers, I had a hunch to just ignore the 13 ohm resistor at the bottom, and somehow got this right. The answer is B. The current running through the 3 ohm resistor is the sum of the currents of the 2 ohm and 1 ohm resistors.
But I don't understand why the 13 ohm resistor can just be ignored. How would the 13 ohm resistor be characterized in the following circuit? Because it didn't factor into any calculations, it doesn't seem to be in series/parallel with any of the other resistors.
