If a circuit has a voltage of 10 volts and a resistance of 2 ohms, what is the current?

To determine the current in a circuit based on the voltage and resistance, you can apply Ohm's Law, which states that the current (I) is equal to the voltage (V) divided by the resistance (R). The formula is:

I = V/R

In this scenario, the voltage is given as 10 volts and the resistance is 2 ohms. Plugging in these values into the formula:

I = 10 volts / 2 ohms

I = 5 Amperes

This calculation indicates that the current flowing through the circuit is 5 Amperes. Understanding this relationship between voltage, current, and resistance is fundamental in electrical circuits and highlights how these elements interact.

The other options provided are either results of incorrect calculations based on misunderstanding the relationship defined by Ohm’s Law or applying incorrect mathematical operations. This reinforces the importance of accurately applying the formula to arrive at the correct answer.
