Question

A heater working in 240V mains consumes 0.5A current

a. Calculate the quantity of charge flowing through the heater coil

for 5 minutes.

b. Calculate the resistance of the heater.

c. Find the quantity of heat generated in the heater when worked

for 5 minutes.​

Answer 1

Answer:

Given = V = 240V

I = 0.5 A

t = 5 min = 5 × 60s

. . = 300s

Q = It

= 0.5 × 300

= 600 C

R = V/I

240 / 0.5

= 480 Ohm

H = I^2R

= 0.25 × 480

= 120J
