How to Calculate Resistance in a Light Bulb Circuit

What is the formula to calculate resistance in a light bulb circuit?

Given the voltage of a light bulb is 1.5 V and current running through it is 2.5A.

Answer:

The resistance of the light bulb is 0.6 ohm.

Calculating resistance in a light bulb circuit involves using Ohm's Law, which states that resistance (R) is equal to voltage (V) divided by current (I), R = V/I.

In this case, the voltage is 1.5 V and the current is 2.5 A. So, by substituting these values into the formula, we get:

R = 1.5 V / 2.5 A = 0.6 ohm

Therefore, the resistance of the light bulb in the circuit is 0.6 ohm.
