Question

an electric heater resistance 8 ohms takes current 15 ampere from main supply line calculate rate at which heat produced in heater​

Answer 1

Explanation:

Here the rate at which energy is dissipated is called power

P=VI

substituting V as IR according to ohms law

we will get P=I^2R

I=15 A

R=8ohms

15×15×8=1800W
