Answer to Question #99078 in Electric Circuits for Komathi

Question

100 Watt 200 volt find current and resistance

Answer 1

Let current = I ,

Resistance = R

Voltage V = 200 volt

Power ,. W = I V

Or. 100 = I x 200

Or, I = 100 / 200 = 0.5 Amp

Now , V = I R

So,. 200 = 0.5 x R

So,. R = 200 / 0.5 = 400 ohm
