Question

A complete circuit contains two parallel-connected devices and a generator for providing the electromotive force. The resistance of the first device is 12 ohms, the resistance of the second device is 4 ohms, and the voltage developed by the generator is 40 V. What is the magnitude of the current flowing through the first device?

A. 10 A
B. 3.33 A
C. 8 A
D. 13.32 A

im guessing b?

Answer 1

Your are correct!
current for 40 volts across 12 ohms:
40V/12 ohms=3.33 smps

Answer 2

oops...
I meant amps.

Answer 3

thanks ;D
