i. Battery- It is used to provide power to various elements of the circuit.

It stores energy or power generated by the generator.

ii. Ammeter- It show the current drawn from the battery by various elements and current provided to the battery from the generator.

iii. Generator - It provide power which is used to charge the battery and to run the other various elements of the vechicle. When the vehicle is in motion the coil inside the generator rotates and it generates power.

3. Load current = 10A

The rating of the fuse current sould be heigher(say 120%-135%) than the the load current

therefore fuse rating should be of 12A or 15A

4. Load Power = 500W

If we take 12V battery

Voltage = 12V

current = 500W/12V

= 41.666A

or we can take battery of capacity available in the market which must be closset to 42Ah or heigher.

5. Bttery and generator are connected in parallel to each other because the potential difference between them should be same.

6. Ignition Switch and Ignition coil is connected in series to each other because the when the switch will be turned on then the circuit will be colsed and the current will flow to the coil.
