The parallel combination of a 330 Ω resistor and a 470 Ω resistor is connected in series with the parallel combination of four 1 kΩ resistors. If a 100 V source is connected across the circuit, then which resistor drops the most voltage?
A)330 Ω
B)470 Ω
C)1 kΩ

Question

The parallel combination of four 1 kΩ resistors results in a lower equivalent resistance than the parallel combination of the 330 Ω and 470 Ω resistors. Therefore, the 1 kΩ resistors in parallel will have a higher voltage drop across them when connected in series with the other combination.
