Name the electrical device that converts mechanical energy into electrical energy. Draw the labelled diagram and explain the principle involved in this device.

For an internal combustion engine to move a vehicle down the road ,it must convert the energy stored in the fuel into mechanical energy to drive the wheels. In your car, the distributor and battery provide this starting energy by creating an electrical "spark", which helps in combustion of fuels like gasoline. Below is the reaction depicting complete combustion of gasoline in full supply of air: 2C_8 H_(18)(l) +25 O_(2) (g) to 16 'x' Identify the types of chemical reaction occurring during the combustion of fuel
