Question

The yellow wire connected to a power supply carries 12v. if the power supply provides 60w of power to the yellow wire, how much current is passing through the yellow wire?

Answer 1

In physics, the rate of power in Watts could be determined by multiplying the voltage in volts, by the current in Amperes. In equation, that would be

P = IV

Substituting the values into the equation,

60 W = I*12V
I = 60/12
I = 5 Amperes

Therefore, a current of 5 Amperes is passing through the yellow wire.
