Question

If the current moving through the filament of a light bulb is 0.5 amps when the voltage across the bulb is 120 volts, what is the resistance of the bulb

Answer 1

The resistance of the bulb is 240 ohms.

Step-by-step explanation:

The resistance of the bulb can be calculated using Ohm's Law, which states that resistance (R) is equal to voltage (V) divided by current (I).

So in this case, the resistance of the bulb (R) can be calculated as R = V / I = 120 V / 0.5 A = 240 ohms.

Therefore, the resistance of the bulb is 240 ohms.
