Calculate the power across each 20 ohm resistance.(a) 1000W, 1000W(b) 500W, 500W(c) 1000kW, 1000kW(d) 500kW, 500kW |

Answer» Correct choice is (b) 500W, 500W The explanation is: This is a series connected circuit hence the current across each resistance is the same. To find current: I=V/R=200/20=5A. To find power: P=I^2R=5^2*20=500W. Since both the resistors have a resistance of 20 ohms, the power across both is the same. |
