Question

(b)Calculate the resistance of heater of rating 600 W -120 V​

Answer 1

Answer:

the resistance in the circuit is 24 ohm

Explanation:

we are given that

power = 600 W

potential differences = 120 V

Power = potential difference × current

P=VI

600 = 120 ×I

I= 5 Amphere

from Ohm 's law we know that

V=IR

120 =5 ×R

R = 24 ohm

so the resistance is 24 ohm
