Two resistors when connected in series to a 120-VV line use one-fourth the power that is used when they are connected in parallel.

Part A

If one resistor is 2.6 kΩkΩ , what is the resistance of the other?

Expert Solution

Let the other resistance is X.

Let the equivalent resistance for series connection is R_s.

Let the equivalent resistance for the parallel connection is R_p.

Let the power for series connection is P_s.

Let the power for the parallel connection is P_p.

The value of equivalent resistance for series is

The value of equivalent resistance for parallel is

We know the power is inversely proportional to the equivalent resistance when the supply voltage is constant.

The value of other resistance is 2600 or 2.6 k.
