Potential difference and power — practice question

As shown, a battery of electromotive force (e.m.f.) $12\,\text{V}$ and negligible internal resistance is linked to three resistors, each with resistance $6.0\,\Omega$. Calculate the power dissipated in resistor $R$.

  • A$2.7\,\text{W}$
  • B$6.0\,\text{W}$
  • C$11\,\text{W}$
  • D$24\,\text{W}$
