Ans:-2) A>BATTERY : Battery is a device which converts chemical energy into electrical energy by means of electron flow between two electrodes.

PRIMARY BATTERY TYPES & USES: 1. Zn-C which is used in remote,toys etc.

2. Mg-MnO2 battery having high capacity, uses in aircraft radios. 3. Mercury-Zinc(Zn-HgO), having very high capacity, uses in hearing-aid, pacemaker,photography etc.

4.Alkaline (Zn-Alkaline), which is for higher performance 5.Zn-Ag2O type, having higer capacity for bio-medical use.

6.Lithium with Solid/solubale cathode, having high energy density(1 to 10000Ah). It is used for Electric Vehicles.

B>AMMETER: Ammeter is a electrical gauge to measure the current flow. C>FUSE: A safety device to protect an electrical circuit from overflow of the current.

Ans:-3)Fuse Rating=10Amp

Ans:-4)Given; Load=500W, Battery of =12 volt

P=VXI > 500=12XI >I=41.66Amp >With factor of safety to get 500W for 1 hr Battery rating=50Amph.

Ans:-5) Two Sealed Beam Light are in parallel to get the full voltage to iluminate.

Ans:-6) Gas Tank Unit and Fuel Gauge are in series so that signal from the tank by means of voltage shows exactly the same value at the gauge and tank about the fuel.
