# Calculating Resistance of a Lamp

## Understanding Ohm's Law:

**Ohm's Law**states that the current flowing through a conductor between two points is directly proportional to the voltage across the two points. The formula for Ohm's Law is

**V = IR**where

**V**is the voltage,

**I**is the current, and

**R**is the resistance.

## Calculation:

Given that the current flowing through the lamp is 5 amps and the voltage is 110 V, we can use Ohm's Law to calculate the resistance.Using the formula

**V = IR**, rearrange it to solve for resistance:

**R = V / I**.

Plugging in the values:

**R = 110V / 5A = 22 Ohms**.

## Conclusion:

The resistance of the lamp connected to a 110v power source is**22 Ohms**. This calculation demonstrates how Ohm's Law can be applied to determine the resistance in an electrical circuit.
