A Simple Circuit Problem: Calculating Resistance of a Light Bulb
Problem:
Use R = to solve this problem.
Question:
What is the resistance of the light bulb in the circuit?Answer:
Resistance of the light bulb = 1.33 ohm (Approx.)Explanation:
Given:
Current in electric bulb = 2 Amp
Voltage in battery = 1.5 Volt
Find:
Resistance of the light bulb
Computation:
Resistance = Voltage / Current
Resistance of the light bulb = Voltage in battery / Current in electric bulb
Resistance of the light bulb = 2 / 1.5
Resistance of the light bulb = 1.33 ohm (Approx.)
