A technician creates a simple circuit that has a 9 V light bulb attached to a 9 V battery. The power output of the light bulb is 100 W. Which equation should be used to calculate how much current in amps is required to achieve the full 100 W output from the 9 V bulb?
|
|
I = P/V = 100W/9V = 11.11A
|
|
I = P*V = 100W*9V = 900A
|
|
I = (P/2)*V = 50W*9V = 450A
|
|
I = P*2*V = 100W*(9V + 9V) = 8100A
