Problem

A 10 Ω10\,\Omega resistor is connected to a 5 V5\,\text{V} ideal source and dissipates a power P0P_0. If the source voltage is raised to 10 V10\,\text{V} with the same resistor still connected, the new power is (a) 5.0 W5.0\,\text{W} (b) 20.0 W20.0\,\text{W} (c) 10.0 W10.0\,\text{W} (d) 2.5 W2.5\,\text{W}
