What would be the current in the lightbulb in Example 4.6 if it sustained a voltage drop

Question:

What would be the current in the lightbulb in Example 4.6 if it sustained a voltage drop of 120. V and required a power of 100. W?

Example 4.6

A battery sustains a voltage drop of 3.0 V across a small lightbulb and produces a current of 0.1 A through the lightbulb. What is the power required by the lightbulb?

Need: Power of lightbulb in watts (W).

Know: Voltage across bulb is 3.0 V. Current through lightbulb I = 0.1 A.

How: Use Equation (4.7), P = I × V, that is, power ¼ voltage [1] current.
