A 12 V battery is connected to a circuit with a 6 Ω resistor. What is the current through the resistor?

Answer :

The current through a 6ω resistor connected to a 12 V battery is 2 A, calculated using Ohm's law.

The current through a resistor in a circuit can be determined using Ohm's law, which states that the current (I) flowing through a circuit is equal to the voltage (V) across the resistor divided by the resistance (R) of the resistor. In this case, a 12 V battery is connected to a 6 ω resistor. Therefore, the current I can be calculated as follows:

I = V / R

I = 12 V / 6ω

I = 2 A (amperes)

The current through the resistor is 2 A. This illustrates a direct practical application of Ohm's law in determining how circuit parameters such as voltage, resistance, and current interact within an electrical circuit.
