Hey,
I have a question to ask and was wondering if you guys could help me.
5.) A computer has a 300-W power supply. If household voltage is 120 V, how much current will flow through the computer?
A. 0.4 A
B. 2.5 A
C. 180 A
D. 420 A
E. 36,000 A
I picked B. I used the equation Electric power= current x voltage and changed it so current=power/voltage...which is how i got 2.5 A.
thanks,
mark
