Question

What is the current in a circuit if the voltage is 120 volts and the wattage is 380 watts?

Answer 1

WE KNOW THAT

                 POWER =  voltage *  current  

here POWER = 380 watts;

       voltage  =  120 volts.

       CURRENT = POWER/VOLTAGE;

      

       CURRENT= 380/120;

           CURRENT=3.16  amperes

                            

            

Answer 2

Current times volts equal watts.(assuming a power factor of one)

I x 120 = 380

I = 380 / 120 = 3.167 amps

The current in the circuit is 3.167 amperes

Answer 3

Voltage divide by watts

Answer 4

W = E*I, so rearranging things a bit we get I = W/E.

(E is voltage, I is current, W is wattage.)

So, 380W / 120V = 3.17 A.
