Three resistors,each of different value,are used in a circuit with a power source supplying 12 volts.For which of the following resistor combinations is the total power supplied the greatest?
A)all three resistors in series
B)all three resistors in parallel
C)two of the resistors in parallel with the third resistor in series with the parallel pair
D)This cannot be found until it is known which resistor is in series with the parallel pair.

When resistors are in parallel, the total resistance is reduced, and more current flows through the circuit. This means that more power is being supplied to the circuit. Therefore, with all three resistors in parallel, the total power supplied is the greatest.
