To find the resistance of the light bulb using Ohm's law, we need to know the voltage across the light bulb and the current flowing through it. Let's assume the voltage across the light bulb is V volts and the current flowing through it is I amperes.
Ohm's law states that V = I * R, where R is the resistance of the light bulb.
Rearranging the equation to solve for R, we get R = V / I.
So, if the voltage across the light bulb is 10 volts and the current flowing through it is 0.5 amperes, the resistance of the light bulb would be:
R = 10 / 0.5
R = 20 ohms
Therefore, the resistance of the light bulb is 20 ohms.
