In a circuit with a voltage of 6 volts and resistance of 15 ohms, what is the calculated current?

To determine the current in a circuit when given the voltage and resistance, Ohm's Law is applied. Ohm's Law states that current (I) is equal to voltage (V) divided by resistance (R). The formula can be expressed as:

I = V / R

In this case, the voltage is 6 volts and the resistance is 15 ohms. Plugging these values into the formula gives:

I = 6 volts / 15 ohms = 0.40 amps

This calculation shows that the current flowing through the circuit is 0.40 amps, making this option the correct answer. By understanding this relationship, one can easily manipulate the equation to solve for current, voltage, or resistance when any two of these values are known.

The other options present currents that do not match the result obtained by using Ohm's Law with the given voltage and resistance, which is why they are not valid.
