What is the driving voltage if a circuit produces 2 Amperes of current at 10 Ohms resistance?

To find the driving voltage in a circuit, you can use Ohm's Law, which states that voltage (V) is equal to current (I) multiplied by resistance (R). In this case, the current is given as 2 Amperes and the resistance is 10 Ohms.

Using the formula:

V = I × R

we can substitute the provided values:

V = 2 A × 10 Ω = 20 Volts.

Given that the correct result of this calculation is indeed 20 Volts, this means that the choice of 15 Volts is not reflective of the relationship defined by Ohm’s Law. The actual driving voltage that produces a current of 2 Amperes at a resistance of 10 Ohms is 20 Volts, which is why it is the right answer. The other choices do not match the necessary calculation outcome based on confirmed electrical principles.
