Question
How much power is delivered by a voltage of 12 volts DC and a current of 2.5 amperes?
Answer Options
- A) 4.8 watts
- B) 30 watts
- C) 14.5 watts
- D) 0.0208 watts
Correct Answer: B
Explanation
Again, using the power formula, P = E \times I (T5C08).
P = 12\text{ V} \times 2.5\text{ A} = 30\text{ Watts}. This calculation gives you the electrical power consumed by a low-power accessory or a handheld radio operating at its maximum output setting.
