Ans.2

1. Battery

Purpose:

A battery is device which store chemical energy and its convert to electrical energy.There is chemical reaction between of two in Cathod , Anode or Electrons in which current pass from it and that can be used to operate output.

Working :

There is chemical reaction between Cathod and Anode and the electrolyte. where Anode is negative and Cathod is positive.

during reaction electrons are produced at Anode . This results electrical differance between Cathod and Anode. When wires get closed . Current again pass in Anode from Cathod and during this process bulb will operated.

2. Generator.

Purpose.

Generator is device which convert form of Energy which may Mechanical or Chemical to Electrical Energy.

Working:

When conductor moves in a magnetic field ,an emf is induced across the conductor .This is basis by rotation of conductor electric generator work.During rotation , each side of the loop comes under magetic north pole and south pole alternately.

3.Fuse.

Purpose:

The main purpose of fuse is to Protect Electrical devices from Heavy current voltage to prevent Short circuit and unbalanced load.

Working:

The fuse is work on the basis of the heating effects of the Electric current . Its one type of wire which is non flammable.When huge electricity pass through fuse there is heat produced which cause the fuse to melt which leads to the opening of the circuit and blockage of current .

Ans. 3

Given,

load = 10A

Voltage = 12V

Power = Voltage * Current

=12V * 10A

= 120W

Fuse rating is approximately 20% more than actual power rating

Power for fuse rating = 120 * 1.20

= 144W

I = P/V

= 144/12

= 12A

Fuse rating maybe 12A.

Ans.4

Given,

Power = 500W

Voltage = 12V.......Recommend

P = V * I

500 = 12 * I

I = 500/12

= 41.67A

Capacity = Curent * time

= 41.67 * 1 hour

= 41.67 Ah

Ans. 5

Current and Voltage regulator

Generator

As per above diagram voltage and current are connected with generator in paraller connection. An electric current can flow though multiple path in parallel circuit.

Ans. 6

Series connection between

Distributor - more than two nodes share and transmitting same power through them.

Starter - connected in series with battery to same current flow through them.
