on vidio series and parallel circuits wiring

 
A series testing board is a simple and very useful board for testing and further we use this board for different types of testing such a connectivity test short circuit test motor winding resistance etc in a series testing board we have a 2 pin outlet or plug socket which is connected with a light bulb.
what is parallel line
A parallel circuit comprises branches so that the current divides and only part of it flows through any branch the voltage or potential difference across each branch of a parallel circuit is the same but the currents may vary.
