Question

resistance of a 230 V heating device is 460 ohm.clculate the heat energy produced by it in 10 minutes.

Answer 1

Answer:

69000J

Explanation:

Given,

v = 230V

t = 10min = 10x60 = 600s

r = 460Ω

H = ?

I = v/r = 230/460 = 0.5 ampere

H = l^2rt

= (0.5)^2 x 460 x 600

= 69000J

Hope it helps you!
