Question
Define electric flux. Write its S.I. units. A spherical rubber balloon carries a charge that is uniformly distributed over its surface. As the balloon is blown up and increases in size, how does the total electric flux coming out of the surface change? Give reason.
✓

Answer

Electric flux is the total number of electric field lines passing normally through a given surface.
Alternate Answer
Electric Flux $\int_{s}\vec{\text{E}}.\text{d}\vec{s}$
S.I. unit $Nm^2/C$
Alternate Answer
V.m No Change
As the total charge enclosed remains the same.
