Question

an electric heater of resistance 8ohm draws current 15 ampere when time is 2hrs .... what is rate of heat produced all concentrate I ll mark u brainliest​

Answer 1

Answer:

Here Given that Resistance of the electric heater (R) = 8 Ω

Current drawn (I) = 15 A

We know that P = I2R

                         = 15×15×8

                          = 1800w or J/s

∴ Heat is produced by the heater at the rate of 1800 J/s.

Pls mark as brainliest

Answer 2

Answer:

Heat is produced around 1800 kj
