1Battery : battery is a device that store chemical energy snd converts it to electrical energy. The chemical reactions in a battery involve the flow of electrons from one material (electrode) to another, through an external circuit. The flow of electrons provides an electric current that can be used to do work.

Working when a battery is supplying power, its positive terminal is the cathode and its negative terminal is the anode The terminal marked negative is the source of electrons that will flow through an external electric circuit to the positive terminal. When a battery is connected to an external electric load, a redox reaction converts high energy reactants to lower energy products and the free electrons difference is delivered to the external circuit as electrical energy

2. Generator : generator is a device that converts motive power into electrical power for use in an electrical circuit.

Working : Generators dont actualy create electricity instead they convert mechanical or chemical energy into electrical energy.they do it by capturing power of motion and turning it into electrical energy by forcing electrons from the external throgh an electrical circuit

3 Ammeter : ammeter is used to measure wide range of current values because at high value only small portion of the current is directed through the meter mechanism.

Ans3. If the load is 10Ampere the recommended fuse is 15Ampere .10A is usually not a safe minimum,the potential impulses or even small fluctuations as a fuse is designed to not exceed the restriction on the current to prevent damage of circuit.

Ans.4

Required power is 500 W × 1h =500whr

So, assuming a DC source of 12 V, the load Ah of battery is 500/12 = 500/4 = 41.66Ah. So a 50 Ah, 12V battery will suffice.

Ans5. Dome light & tail stop are connected in parallel .In parallel the positive side is connected to positive side and negative side is connected to all the negative side so it increases the run time while maintaining the voltage where voltage remains the same

Ans6. Fuse and Ammeter are connected in series,Fuse is a electrical protection device built around a conductive strip that is designed to melt in case of excessive current flow.fuse are always connected in series with the circuit to be protected from excessive current. when the fuse blow it will open the entire circuit and interrupt or stop the flow of current through the circuit
