To produce100jouls of heat in 10 seconds how much voltage should be applied to 100 ohm resistance

Answer»

⭐hey there!!

Given :

=> W = 100 J, t = 10 SEC

=> R = 100 ohm

=>> V =??

Now we have to find v

POWER (p) = w/t = 100/10 = 10 W

So we know that power(P) = V²/R

➡Where V = voltage.

➡R = resistance

Now, use above formula,..

➡ W = V²/R

➡V² = WR

➡ V = √WR = √1000 = 10√10 = 31.62 volt
