Problem

Resistors

R_{1}=4\,\Omega

and

R_{2}=6\,\Omega

are connected in series across a

24\,\text{V}

source. A third resistor

R_{3}=12\,\Omega

is then connected in parallel with this series combination, the supply voltage remaining

24\,\text{V}

. Approximately by what percentage does the total power consumed by the circuit increase? a)

55\%

80\%

100\%

40\%
