Heya...
Charge free regions
In a charge-free region, electric field lines can be taken to be continuous curves without any breaks....
_______ And ________
The idea is that electric field lines can start on positive charges and finish on negative charges.
In such a case electric field lines would be discontinuous.
With no charges present the electric field lines must be continuous.
