Question

A 65.4-? resistor is connected in parallel with a 136.4-? resistor. This parallel group is connected in series with a 22.6-? resistor. The total combination is connected across a 15.4-V battery. Find (a) the current and (b) the power dissipated in the 136.4-? resistor.

Explanation / Answer

(65.4 x 136.4/(201.8))+22.6 =66.804 ohms ( Equivalent resistance)

Current = Voltage/resistance = 15.4/66.8 =0.23 Amperes

Power = Voltage x Current =3.55 Watts
