Question

resistance of a 230v heating device is 460ohm. calculate the heat energy produced in 10 minutes​

Answer 1

Answer:

Here, resistance, r= 460 ohm

potential difference ,v = 230 v

time, t = 10 min = 600 s

Now, Heat consumed ,H =

$heat \: consumed \: = \frac{ {v}^{2} }{r} \times t$

or, H = (230×230× 600)/460

or, H = 69000 J
