Electricity Calculation Challenge

What is the current flowing through a 60-watt bulb with a supply voltage of 120 volts and a lead wire resistance of 6 ohms?

Final answer: 0.50 Ampere

Given a supply voltage of 120 volts and a lead wire resistance of 6 ohms, the current flowing through a 60-watt bulb is calculated using the power equation. Solving for current gives 0.50 Ampere.

Explanation: In the given question, we're looking at the principles of electricity, particularly how to use Ohm's law and the power formula. When the supply voltage is 120 volts and the resistance of the lead wire is 6 ohms, we want to work out how much current flows through the 60-volt bulb. Solving the power equation P=IV for the current = P/V, we realize that inserting the given values for power (60 watt) and voltage (120 volts), the current is 60W/120V which results in 0.50 Ampere. In summary, a half ampere flows through the lightbulb when 120 V is applied across it.
