How to Calculate Resistance of a Light Bulb in a Circuit
What is the resistance of a light bulb in a circuit with a current of 0.73 Amps and a voltage of 120 Volts?
The resistance of the light bulb is 164.38 Ω
To find the resistance, we will use the formula:
V = I / R
where,
I = current
V = voltage
R = resistance
Given in the question,
I = 0.73 A
V = 120 V
Now, we will put the values in the formula:
R = V / I
R = 120 / 0.73
R = 164.38 Ω
Therefore, the resistance of the light bulb is 164.38 Ω
