Series and Parallel Circuit
A 12 V battery connects to a 4 Ω and a 2 Ω resistor.
(a)2 points
If the resistors are in series, find the current from the battery.
(b)2 points
If instead in parallel, find the equivalent resistance.
(c)2 points
In the series case, find the power dissipated by the 4 Ω resistor.
