9) Electrical  circuits
Aim :– to known the electrical circuits.
 * Types of circuit :-
1) series
2) parallel
1) series connection :- to connect two lamp from one switch .or three lamp from switch .it         means connecting a lamp in line with one connection.
2) parallel connection :- to connect one lamp by one switch .for example house wiring or
     godown wiring .in series we get less brightness from lamp but in parallel we get exact
     Brightness as it is.
* Requirement for connection of the simple circuit .
   For doing both circuit types we required circuit board ,holder and switchs. And types of           bulb of different watt and different watt and wire .tester ,screwdriver, electrical knife ,plier
   Wire cutter
   Observation :- in series voltage get divided.
                             In parallel current get divided.
