Question
Define electric flux. Write its SI 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.
Solution
The total number of electric lines of force passing normally through that area per second is defined as Electric flux.
It is given by:
SI unit of electric flux is Nm2 C–1.
As the balloon is blown up, the total charge on surface of the balloon remains unchanged, so the total electric flux coming out of its surface remains unchanged.
It is given by:
SI unit of electric flux is Nm2 C–1.
As the balloon is blown up, the total charge on surface of the balloon remains unchanged, so the total electric flux coming out of its surface remains unchanged.
