What is the amperage in a 24-volt circuit with 4 ohms of resistance?

To determine the amperage in a circuit, you can use Ohm's Law, which states that current (I) is equal to voltage (V) divided by resistance (R). In this case, the voltage is 24 volts and the resistance is 4 ohms.

Using the formula:

I = V / R

Substituting the given values:

I = 24 volts / 4 ohms

This calculation results in:

I = 6 amps

Thus, the correct answer is indeed 6 amps. This answer demonstrates the application of Ohm's Law effectively: with a higher voltage and a relatively low resistance, the resulting current is significantly higher, confirming the understanding of how voltage and resistance interact to affect current in electrical circuits.
