1) Battery
2) Starter
3) Fuse
4) Regulator
5) Ammeter
6) Generator
7) Distributer
8) Breaker
9) Foot Selector Switch
10) Junction Box

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

Ans.

1) Battery:
Purpose- Battery is a energy storage device. The main Purpose of the Battery is Store the energy and
transform the energy when any energy consumtion devise needed. Batteries are a compact source of
energy. Energy storage is a major problem throughout the world. Batteries solve this problem by
reducing the storage capacity very little and eliminating the need to carry fuel. Batteries are one of the
most convenient ways to store power.
application sectors:
1) hospital and medical devices
2) residencial houses and commercial offices
3) Fire fighting and emergency uses
4) industral machinery and power
5) automobile industrie
6) toys and electronic devices
7) military camp, sites and instruments
8) construction and logistic industries
9) school, colleges and IT industries Complex
10) marine industries
now days electric vehicles demanded most use of battery, Because electric vehicles takes a place of IC
engine vehicles becuase of global warming and reduce the carbon percentage. Battery takes a place of
fuels like petrol, diesel, CNG etc.
Working- Battery is a source of chemical energy means chamical cells. also its have a anode and cathode
which is play a role to transform the chamical energy in to the electric energy.
here all batteries have a three major components- Anode (negative terminal), Cathode ( positive
terminal) and Elctrolyte liquied.When the negative terminal and the positive terminal of a battery are
connected in a circuit, a chemical reaction occurs between the electrolytes and the negative terminal.
This reaction generates electrons that flow through the circuit and get deposited in the positive terminal
i.e., the cathode. When the cathode or anode material is consumed, the reaction stops occurring, and
the battery stops generating electricity. Here the battery is called 'dead'.

2) Generator:
Purpose- Generoter is a energy transformation device which is transform mechanical energy in to the
electric energy. it is mainly used to provide a electical energy for differentt application like domestic,
commercial and indstrial uses.Generoter also uses in automobile vehicles , electric vehicales ,
aeroplance industries, trains and marine ships.
Working- generator is Transform mechanical energy in to the electrical eergy by rotation motion of
element which is turning in to the electrical energy by the electrons transform by external electric
soruce or stator winding. basically generator is a reverse of motor working.

3) Fuse:
Purpose: Fuse is one type of circuit breaker and safeguard device. it is use to stop the hazzardness
during the current flowing from elctric wiring and system. so advantage of this fuse is to prevent all
machine or any human from any short circuit and fire hazzard in electric system.
application sectors
1) residencial, hospital and offices's electric flow
2) electric equipment and automotive industries.
3) construction equipment and industrial machinery.
4) small electric devices
working: fuse is working on delta of temperature generation in electric system. It is composed of a
non-flammable thin metallic wire with a low melting point.
If a high amount of Electricity is passed from the Electric Fuse, there is a production of heat which
causes the Fuse to melt which leads to the opening of the Circuit and the blockage of Current.Once a
Fuse melts, it can be changed or replaced with a new Fuse.A Fuse is normally made up of elements like
zinc, copper, aluminum and silver.A Fuse acts as a circuit breaker and breaks the circuit in case any fault
occurs in the circuit. It acts as a protector of Electric appliances and also as a safety measure for humans.
The figure below represents a Fuse operation, Fuse barrel and Fuse link.

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

Ans.- 13A fuse
Q-4-If 500W is the load, what is the voltage and capacity of battery you recommend?
Ans.
here is Battery capacity = load * time
we have a value of given
1) load =500watt
suppose take a Time= 24 hours
suppose take a voltage= 12 V
so finnaly put the value in equestion
Battery capacity = 500*24 = 12000wh
Amp-hours = Watt-hours / Volts
=12000/12
=1000 AH

Q-5- Identify any two elements which are connected parallel to each other. Why they are connected in
parallel.

Ans.- After study the above image Generator with current voltage and regulaterare connected in parallel
if two are more components are connected in parallel, they have the same differential of potential
voltage across their ends.

Q-6-Identify any two elements which are connected in series. Why they are connected in series?

Ans- After study the above image battery and starter are in series to each other because same current
flows through them
