Project - Analysis of a practical automotive wiring circuit

A generator is a device that converts mechanical energy into electrical energy. Its purpose is to provide a source of electrical power in situations where a connection to a power grid is not available or practical.

The basic working principle of a generator is based on Faraday's law of electromagnetic induction. A generator consists of a stationary component (stator) and a rotating component (rotor). The stator contains a set of coils that are arranged around the rotor, which has a set of magnets attached to it.

When the rotor rotates within the stator, the magnets induce a magnetic field in the coils of the stator. This creates an electric current in the coils, which generates an electrical output from the generator.

The mechanical energy that drives the rotation of the rotor can come from various sources, such as a steam turbine, a gas turbine, a wind turbine, or a diesel engine. The energy is typically transferred to the rotor through a shaft, which is connected to the mechanical source.

The output of a generator can be varied by adjusting the speed of the rotor or the strength of the magnetic field in the stator. The frequency and voltage of the output can also be controlled by adjusting the speed and the magnetic field.

Generators are commonly used in a variety of applications, including backup power systems, construction sites, remote locations, and power plants. They are available in a range of sizes and power outputs, from small portable units to large industrial generators capable of producing megawatts of power.

Breaker

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.

Q3.If the total load is 10A from battery, what should be the fuse rating?

Given data;

Total load(I)=10A

fuse rating=?

Voltage(V)=30V [since the typical Car battery voltage is 30V ]

we know that;

P=V*I

P=30*10

P=300KW

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

I=(300*1.5)/30

I=15A

The fuse rating is more than the maximum load of the appliance to avoid the short circuits or damage of appliance due to over flow of load. we must maintain the fuse rating 25% greater than the total load. so that the fuse rating is to be 15A.

Q4.If 500W is the load, what is the voltage and capacity of battery you recommend?

Given data;

I=10A (from the previous question)

P=500W

V=?

C=?

we know that,

From the power formula,

P=V*I

V=P/I

V=500/10

V=50V

capacity (C)= I*T

=10*1

C= 10Ah

Q5.Identify any two elements which are connected parallel to each other. Why they are connected in parallel?

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

Q6.Identify any two elements which are connected in series. Why they are connected in series?

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

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.
