Question

an electric dc circuit is attached to a 12 volt battery and has a 3 ohm resistor in it what is the current in an ac circuit with 120 volt and a 60 watt light bulb?

Answer 1

ohm's law is
V=R*I

12 volt and 3 ohm
12/3=4 amps

V*I=power
120*I=60 watts
I=.5 Amps
j

Answer 2

I = E/R = 12/3 = 4 amperes But Power= VI = 12*4= 48 watts So, if the rated power of the resistor is any less than 48 watts this will get burned and likely open and no current will circulate!.
