An electric heater of resistance 5 Omega...

An electric heater of resistance `5 Omega` is connected to an electric source. If a current of 6 A flows through the heater, then find the amount of heat produced in 5 minutes.

Text Solution

Verified by Experts

Given resistance `R=5Omega`, Current `I=6A`,
Time `t=5` minutes `=5xx60s=300s`
Amount of heat produced, `H=I^(2)Rt`
`H=6^(2)xx5xx300`. Hence, `H=54000J`
