Question

100 J OF HEAT IS PRODUCED EACH SECOND IN A 4 COULUMB RESISTER. THE POTENTIAL DIFFERANCE ACROSS THE RESISTER WILL BE

Answer 1

The correct answer is "20 Volts".

Step-by-step explanation:

Given:

Heat,

H = 100 J

Resistance,

R = 4 Ω

As we know,

⇒
`P=(v^2)/(R)`

By putting the values, we get

⇒
`100=(v^2)/(4)`

⇒
`v^2=100* 4`

⇒
`=400`

⇒
`v=√(400)`

⇒
`=20 \ volts`
