Solution to Assignment 4
... Solution: Since the current through the 3R resistor is 12 A, the voltage across it is V = I R = 12 * 3R= 36R. Since the 6R and 3R resistors are in parallel, the voltage across the 6R resistor is also 36R. It follows that the current through the 6R resistor is 36R/6R=6A. The current that flows throug ...
