How much power is delivered by a voltage of 12 volts DC and a current of 2.5 amperes?

To find the power delivered when you have a voltage of 12 volts and a current of 2.5 amperes, you can use the power formula:

Power (P) in watts is calculated by multiplying the voltage (V) in volts by the current (I) in amperes.

In this case, the calculation would be:

P = V × I

P = 12 volts × 2.5 amperes

P = 30 watts

Therefore, the correct answer is 30 watts. This formula is fundamental in electronics and helps to quantify how much energy is being used or delivered in a circuit. The other options represent values calculated from different voltage or current combinations but do not give the accurate power derived from the specified voltage and current in the problem.
