Question

100 joule of heat are produced each sound in a 4 ohm resistance. Find the potential difference across the resistor..

Answer 1

Heya !!!


here is your answer !!!


Power = (potential difference )² / resistance

or


P = V² / R


=> 100 = V² /4 Ω


V² = 100 * 4 Ω


=> V = √ 400


V = ± 20 .


hence the potential difference across the resistor is. 20 voltage


hope it helps you dear!!!


thanks !!
