- The power dissipated in a resistor is given by P = V2/R, which means power decreases if resistance increases. Yet this power is also given by P = I2R, which means power increases if resistance increases. Explain why there is no contradiction here.arrow_forwardThree 60.0-W, 120-V lightbulbs are connected across a 120-V power source, as shown in Figure P18.50.
