Currents

In a series circuit the same current flows through each part of the circuit .there is only one part of the circuit ,there is only one path for the current to flow round .circuits a and B are series circuits.

In a parallel circuit the current divides when it comes to a junction .part of the current flows through the other brnch. Part of it flows through the other .the bullos in circuits (and) are joined in para kel .

When two branches have the same resistance,the same current flows through each branch.
