I am struggling with this series circuit. A classmate and I are confused. I think It = 15Amps like the circuit shows but my class mate thinks it should read It = 1.5 Amps.
My math:
IR2 = E/R = 120v / 25Ω = 4.8A
IR3 = E/R = 120v / 25Ω = 4.8A
Combine IR2 + IR3 = 9.6 Amps
Now subtract this from It. 15A - 9.6A = 5.4Amps.
R1 = E/I = 120v / 5.4A = 22.222Ω so R1 = 22.222Ω
Rt= 25Ω + 25Ω + 22.222 = 72.222Ω
4.8A + 4.8A + 5.4A = 15Amps Right??????? or Am I wrong????
