Question

The unit of electric flux is:

• A. Volt $\times$ Sec
• B. Volt $\times$ metre
• C. Amp $\times$ Sec
• D. Amp $\times$ metre

Hint:

Electric flux connects electric field with surface area. Its SI unit is Volt $\times$ metre.

Answer 1

The Correct Option is B

Step 1: Formula of electric flux.
Electric flux is defined as: \[ \phi = \vec{E} \cdot \vec{A} \] where $\vec{E}$ is electric field (unit: Volt/m) and $\vec{A}$ is area ($m^2$).
Step 2: Unit calculation.
So, unit = (Volt/m) $\times$ ($m^2$) = Volt $\times$ metre.
Step 3: Conclusion.
Thus, the correct answer is Volt $\times$ metre.
