A Circuit with a 12 V Battery and Lamp

What is the resistance of the lamp in a circuit with a 12 V battery and lamp carrying a current of 3 A?

The resistance of the lamp in the circuit can be calculated using Ohm's Law, which states that resistance (R) is equal to voltage (V) divided by current (I):

Resistance (R) = Voltage (V) / Current (I)

Given that the voltage (V) is 12 V and the current (I) is 3 A, we can plug in these values to find the resistance:

R = 12 V / 3 A

R = 4 ohms

Therefore, the resistance of the lamp in the circuit is 4 ohms.
