Problem

Two resistors, 6 Ω6\,\Omega and 12 Ω12\,\Omega, are connected separately across the same 12 V12\,\text{V} battery. Which statement about the power dissipated in the resistors is correct? (a) The 12 Ω12\,\Omega resistor dissipates twice the power of the 6 Ω6\,\Omega resistor. (b) Both resistors dissipate equal power. (c) The 6 Ω6\,\Omega resistor dissipates twice the power of the 12 Ω12\,\Omega resistor. (d) The 6 Ω6\,\Omega resistor dissipates four times the power of the 12 Ω12\,\Omega resistor.
