Question

A simple circuit for two element electrin heater with a 120v power source,find the total current supplied by the power source if the resistors are 30 ampere and 60 ampere,find the total resistance of the circuit

Answer 1

Answer:

V=200 V

I=0.5 A

By ohm's law :

V=IR

R=V/I=200/0.5=400 ohms

power=VI=200*0.5=100 Watts.
