What is the voltage in a circuit with 3 ohms of resistance and a current of 6 amperes?

To determine the voltage in the circuit, you can use Ohm's Law, which states that voltage (V) is equal to the product of current (I) and resistance (R). This can be expressed with the formula:

[ V = I \times R ]

In this scenario, the resistance is 3 ohms and the current is 6 amperes. Plugging these values into the formula gives:

[ V = 6 , \text{amperes} \times 3 , \text{ohms} = 18 , \text{volts} ]

This calculation shows that the voltage in the circuit is 18 volts, confirming that the correct answer is indeed based on the correct application of Ohm's Law. Understanding this principle is crucial for analyzing electrical circuits effectively, as it provides a fundamental relationship among voltage, current, and resistance in electrical systems.
