Calculate the resistance and current of an incandescent light bulb

What is the power output of the light bulb?

The power output of the light bulb is 100W.

What is the voltage of the power source?

The voltage of the power source is 110V.

Calculate the resistance of the light bulb.

Calculate the current drawn by the light bulb.

Answer:

Resistance: 121Ω

Current: 0.909 A

Given the power output of the light bulb is 100W and the voltage of the power source is 110V, we can calculate the resistance and current drawn by the light bulb.

First, we calculate the resistance using the formula:

Resistance = Voltage^2 / Power

Substitute the values:

Resistance = 110^2 / 100 = 121Ω

Next, we calculate the current drawn by the light bulb using the formula:

Current = Power / Voltage

Substitute the values:

Current = 100 / 110 = 0.909 A

Therefore, the resistance of the light bulb is 121Ω and the current drawn by the light bulb is 0.909 A.
