Question no.2

Battery

purpose-Batteries are small essential components to operate many devices. It is one of the key components in our day-to-day life. Some batteries are rechargeable batteries and are used in each and every sector. Below are some of the applications of batteries.

• Automotive
• House
• Health Instruments
• Medical
• Logistics and construction
• Firefighting and Emergency
• Military

working- 

• A battery is a device that stores chemical energy and converts it to electrical energy.
• The chemical reactions in a battery involve the flow of electrons from anode to cathode. 
• The flow of electrons provides an electric current that can be used to do work.
• To balance the flow of electrons, charged ions also flow through an electrolyte solution that is in contact with both electrodes.
• Different electrodes and electrolytes produce different chemical reactions that affect how the battery works, how much energy it can store and its voltage. 

Generator

Purpose- generator is also called a dynamo, it converts mechanical energy into electricity for transmission and distribution over power lines to domestic, commercial, and industrial customers. Generators also produce the electrical power required for

• automobiles
• aircraft
• ships
• trains

working-

Generators actually create electricity. they convert mechanical or chemical energy into electrical energy. They do this by capturing the power of motion and turning it into electrical energy by forcing electrons from the external source through an electrical circuit. A generator is essentially an electric motor working in reverse.

Fuse

Purpose-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. If the current going through the fuse is too great the wire heats up until it melts and breaks the circuit

working-

The fuses work on the principle of the heating effect of the current. It’s made up of thin strip or strand of metallic wire with noncombustible material. This is connected between the ends of the terminals. Fuse is always connected in series with the electrical circuit.

When the excessive current or heat is generated due to heavy current flows in the circuit, the fuse melts down due to the low melting point of the element and it opens the circuit. The excessive flow may lead to the breakdown of wire and stops the flow of current. The fuse can be replaced or changed with the new one with suitable ratings. The fuse can be made up of the element like zinc, copper, silver &aluminum. They also act as a circuit breaker which is used to break the circuit when the sudden fault occurs in the circuit. This is not only a protector but it is also used as a safety measure to prevent humans from hazards. So this is how the fuse operates.

Question no.3

we can use 13A fuse for above given question

Question no.4

Capacity=load*time

load given=500watt

Time        =24hours

average  of voltage= 12v

capacity=500*24=12000wh

Amp-hours = Watt-hours / Volts  =12000/12=1000AH

Question no.5

Asper the above image Generator with current voltage and regulaterare connected in parallelif two are more components are connected in parallelthe have the same differential of potential voltage across their ends.

Question no.6

as per the above image battery and starter are in series to each other because same current flows throw them.
