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.
