How to Calculate Current Flowing Through a Lamp in a Household Circuit

What is the resistance of the lamp and the voltage in the household circuit?

Given: The resistance of the lamp is 60 Ohms. The voltage in the household circuit is 110 Volts.

How do we calculate the current flowing through the lamp?

Options: A) 0.55 A B) 1.83 A C) 170 A D) 6,600 A

Answer:

The current through the lamp can be calculated using Ohm's law:

i = V / R

Where:

i = current

V = voltage

R = resistance

Substitute the values of resistance and voltage into the formula:

i = 110 / 60 = 1.83 A

Therefore, the current flowing through the lamp is 1.83 Amperes.

Explanation:

When a lamp with a resistance of 60 Ohms is plugged into a 110-Volt household circuit, we can determine the current flowing through the lamp by applying Ohm's law.

Ohm's law states that the current flowing through a circuit is equal to the voltage across the circuit divided by the resistance of the circuit.

In this case, the voltage across the lamp is 110 Volts and the resistance of the lamp is 60 Ohms.

By substituting these values into the formula i = V / R, we get:

i = 110 / 60 = 1.83 Amperes.

Therefore, the current flowing through the lamp in the household circuit is 1.83 Amperes.
