Question

If you have a 500 watt lightbulb and the wall socket provides 120 Volts, what is the current? Explain.​

Answer 1

Answer: To calculate the current, we can use the formula I = P/V, where I is the current, P is the power, and V is the voltage.

For a 500 watt lightbulb and a 120 volt wall socket, the current would be:

I = P/V

I = 500/120

I = 4.17 amps

Therefore, the current would be 4.17 amps.

This formula is derived from Ohm's law, which states that the current through a conductor between two points is directly proportional to the voltage across the two points and inversely proportional to the resistance between them. In this case, the resistance of the lightbulb is not given, but we can assume that it is constant. By knowing the power and voltage, we can use the formula to calculate the current.
