Question

How much power is used by a circuit having 200 volts applied and 2.5 amperes of current flowing through it

Answer 1

Watts = Volts x Amps = 200 x 2.5 = 500Watts = 0.5kW.

Answer 2

power= voltage*current

p = v*I

p=200*2.5

p=500 watts

Answer 3

If its dc then the equation P=VI (200 X 2.5) = 500W would be correct but you don't specify if its dc or ac.

I am amazed at the number of people on here that think P=VI in ac. It doesn't unless the load is purely resistive so the type of voltage always needs to be stated.

Answer 4

220 Volts x 2.5 Amps = 500 Watts.

Answer 5

P = IV

I = 2.5

V = 200

P = 200 * 2.5

P = 500 Watts

Answer 6

Power = EI = 200 volts x 2.5 amperes = 500 kW.

Answer 7

Look up "Ohms law", V=IR, P=VI, I=V/R, R=V/I

R= resistance

P=power

I= current

V=volts

Answer 8

Volts x Amps = Watts

So, 200 x 2.5 = 500.
