Project - Analysis of a practical automotive wiring circuit

1) Battery,Ammeter,generator,switches,current and voltage regulator,earthing,parking lamps, horn, ignition coil, distributor etc

2) battery : It is the source of electrical energy. Battery stores electrical energy in the form of chemical energy and discharge the required amount of current within battery rating

Earthing: it is used to eliminate the excess current in the circuit which may destroy the battery as well as devices connected to battery

Ammeter : it is the device that measure current in the circuit and helps to identify the state of charge of battery

generator: it is the device that converts mechanical energy into electrical energy. It generates current and keep charging the battery until engine is running usually it may be alternator or dynamo

current and voltage regulator: it is the device that regulates the charging current and voltage and ensure charging is done within C rating

Switches:switches helps in closing and opening the circuit

3)Fuse must be within 10A to 15A

4) If P = 500 W then I suggest 24V 42 Ah battery so that at least power can be supplied for 2 hours

5) two elements that are connected in parallel are horns and head lamps because both lamps offers same resistance and same voltage should flow to them so they are connected in parallel

6)two elements that are connected in series are (ammeter battery charger) and (fuel guage and tank) because the potential difference indicates the state of charge on battery and fuel in fuel in fuel tank
