Question
Two light bulbs for use at $110 \mathrm{~V}$ are rated at $60 \mathrm{~W}$ and $100 \mathrm{~W}$ respectively. Which has the filament with lower resistance?
Step 1
Step 1: We know that the resistance R of a bulb can be calculated using the formula: \[ R = \frac{V^2}{P} \] where V is the voltage and P is the power. Show more…
