Question

.Two heaters A and B each working with 230V for 5 minutes generates heat energy. Heater A has resistance 100 ohm and Heater B has resistance 1000 ohm.Which heater will generate more heat? ​

Answer 1

Answer:

heater A will generate more heat then B

Explanation:

for A

pd= 230v

time 5 mint= 300sec

R=100 ohm

so using formula

H=V^2t/R

so after simplify

it would be 158700J

as same for heater B value is same so just pit in given formula we will get

H= 15870J

so heater A will generate more heat.
