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
