Sagot :

Cricetus

Answer:

The correct answer is "20 Volts".

Explanation:

Given:

Heat,

H = 100 J

Resistance,

R = 4 Ω

As we know,

⇒ [tex]P=\frac{v^2}{R}[/tex]

By putting the values, we get

⇒ [tex]100=\frac{v^2}{4}[/tex]

⇒  [tex]v^2=100\times 4[/tex]

⇒       [tex]=400[/tex]

⇒    [tex]v=\sqrt{400}[/tex]

⇒       [tex]=20 \ volts[/tex]
