The current in a lamp is 0.5 ampere when it is plugged into a standard wall outlet. What is the resistance of the lamp when it is plugged into a standard wall outlet?

The resistance of the lamp when it is plugged into a standard wall outlet is 240 Ohms.

Given the following data:

Note: In the United States of America, a standard wall outlet supplies a voltage of 120 Volts.

To determine the resistance of the lamp when it is plugged into a standard wall outlet, we would apply Ohm's law:

Ohm's law states that at constant temperature, the current flowing through an electrical circuit is directly proportional to the voltage (potential difference) applied across its terminals and inversely proportional to the resistance in the electrical circuit.

Mathematically, Ohm's law is given by the formula;

Where;

Making R the subject of formula, we have:

Substituting the given parameters into the formula, we have;

Resistance, R = 240 Ohms

The resistance of the lamp plugged in to a standard wall outlet with a current of 0.5 amps is 240 Ω (ohms)

Explanation:

In the United States Of America the standard voltage is 120 v and their frequency is 60 Hz

Standard wall outlet voltage is 120 V

The current in the lamp is 0.5 ampere

Resistance (R) = V/ I

      = 120/0.5

      = 240Ω (ohms)

Thus the resistance of the lamp plugged in to a standard wall outlet with a current of 0.5 amps is 240 Ω (ohms).

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!
