3 volt × 4 coulom b =
- 12 watts
- 12 amperes
- 12 ohms
- 12 joules
The Correct Option is D
Solution and Explanation
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
