Project - Analysis of a practical automotive wiring circuit

1) Identify each of the major elements in the above automotive diagram.

Ans:

2) Explain the purpose and working of any three elements briefly.

Ans:

Generator: An electric generator is a device that converts mechanical energy obtained from an external source into electrical energy. It uses the mechanical energy supplied to it to force the movement of electric charges present in the wire of its windings through an external electric circuit.
Breaker: A circuit breaker is an electrical safety device designed to protect an electrical circuit from damage caused by an overcurrent or short circuit. Its basic function is to interrupt current flow to protect equipment and to prevent the risk of fire.
Fuse: It is a safety device. The fuse breaks the circuit if a fault in an appliance causes too much current to flow. This protects the wiring and the appliance if something goes wrong. The fuse contains a piece of wire that melts easily.

3) If the total load is 10A from battery, what should be the fuse rating

Ans:

Given date:

Total Load = 10 A

Fuse rating = ?

Assuming V = 30V {due to typical car voltage is 30V

Slov

P = V*I

P = 30*10

P = 300 KW

Fuse rating = I = (P*1.5)/V

I = (3OO*1.5)/30

I = 15A

The fuse rating will be high from load due to avoid short circuit etc..

4)Identify any two elements which are connected parallel to each other. Why they are connected in parallel?

Ans :-

Horn: parallel switching of high and low tones is used and the main sound frequencies of these signals are harmoniously combined.

All lights: Each light in a parallel circuit has its own circuit. The individual currents add up to the total current. The voltage for each light is the same. As opposed to a series circuit, if one light malfunctions in a parallel circuit, the other lights still light up

5) Identify any two elements which are connected in series. Why they are connected in series

Ans :-

Battery: connected in series with high voltage to improve the drivability and energy

Ammeter: An ammeter is a device which measures the amount of current flowing in a circuit. It is a very low resistance (nearly zero) device. If it will be connected in parallel, it would draw most of the current and would get damaged.
