Discovering Electrical Resistance in a 12v Lamp

What is the resistance of a 12v lamp connected to a 12v battery with a current of 2.0 A?

Calculate the resistance using Ohm's law.

Answer:

The resistance of a 12v lamp connected to a 12v battery generating a current of 2.0 A is 6 ohms.

Electrical resistance is a fundamental concept in understanding the behavior of electrical circuits. When a 12v lamp is connected to a 12v battery and the current flowing through it is 2.0 A, we can calculate the resistance using Ohm's law.

Ohm's law states that resistance (R) is equal to the voltage (V) divided by the current (I), or R = V / I. Given the values of voltage (12 volts) and current (2.0 amperes), we can substitute these values into the formula to find the resistance.

Thus, by applying Ohm's law, we have: R = 12v / 2.0A = 6 ohms. Therefore, the resistance of the 12v lamp at the specified current is 6 ohms, indicating the opposition to the flow of electric current in the circuit.
