Question

Calculate the rate at which heat is developed in the filament of a bulb of resistance
100 Ω such that a current of 0.5A flows through it for 10 minutes.

Answer 1

Answer:

100 Joule

Step-by-step explanation:

Given:

R=100 ohm

I=0.5 Ampere

t=10 minutes=600 seconds

To Find:

Heat,H=?

Wkt;

H=I²RT

H=(0.5)²×100×600

H=0.25×60000

H=15000 Joule.
