A light bulb connected to a 120V source

A light bulb that is connected to a 120 V source draws 1.3 A. What is the resistance of the light bulb?

Final answer:

To calculate the resistance of the light bulb connected to a 120 V source drawing 1.3 A, Ohm's Law is used, and the resistance is found to be 92.31 ohms.

Explanation:

To calculate the resistance of a light bulb connected to a 120 V source and drawing 1.3 A, we can use Ohm's Law, which states that the voltage (V) across an electrical component is equal to the product of the current (I) flowing through it and its resistance (R), expressed as V = IR. To find the resistance, we rearrange the equation to R = V/I.

Using the given values:

    • Voltage (V) = 120 V
    • Current (I) = 1.3 A

We calculate the resistance (R) as follows:

R = 120 V / 1.3 A

R = 92.31 ohms

Therefore, the resistance of the light bulb is 92.31 ohms.

What is the formula to calculate the resistance of an electrical component using Ohm's Law? The formula to calculate the resistance of an electrical component using Ohm's Law is R = V/I, where R is the resistance, V is the voltage across the component, and I is the current flowing through it.
