KIRCHOFF'S LAWS
Kirchoff's laws provide an easeir way to approach complex problems, useful to know especial if you are going to a university interview. They are :

The sum of all currents going into a junction is zero.
The sum of all E.M.Fs in circuit is equal to the sum of all the products of current and resistance.

Alway remember to apply the correct sign to a certain direction of current flow.
