A $3.0 - \Omega$ Resistor Is Connected in Parallel with A $6.0 - \Omega$

Multiple Choice

A $3.0 - \Omega$ resistor is connected in parallel with a $6.0 - \Omega$ resistor. This combination is then connected in series with a $4.0 - \Omega$ resistor. The resistors are connected across an ideal 12-volt battery. How much power is dissipated in the $3.0 - \Omega$ resistor?

A) $12 \mathrm {~W}$
B) $6.0 \mathrm {~W}$
C) $2.7 \mathrm {~W}$
D) $5.3 \mathrm {~W}$
