Question

3 volt × 4 coulom b =

• A. 12 watts
• B. 12 amperes
• C. 12 ohms
• D. 12 joules

Answer 1

The Correct Option is D

The formula for electrical energy is: $$E = V \times Q$$ where:
$E$ is the energy in joules,
$V$ is the potential difference in volts,
$Q$ is the charge in coulombs.
Substituting the given values: $$E = 3 \, \text{V} \times 4 \, \text{C} = 12 \, \text{Joules}$$

Thus, the correct answer is 12 joules.The correct option is (D): $12$ joules
