BRAIN TEASER !!!
The windmill will generate power as the car moves and air blows into it. This power will be used to charge the car’s battery. Can you improve car battery efficiency by attaching the windmill to the top of your electric car?

★ Answer :-
Yes.
The answer is a simple yes. We can improve the efficiency of car battery by attaching the windmill to the top of the car. To understand this, we must look deeply to functioning of Battery of the car and windmill.
----------------------------------------------------------
✒ Car ::
Car Battery produces electrical impulses which provides acceleration to the car. This car battery even support all the light - related problems of car like head lights, inner lights, etc. This battery is re - chargeable that is when its power get low, it can be charged again. This battery also helps in starting of car by igniting the spark plugs of the car.
✒ Windmill ::
Windmill works on the principle of Electromagnetic Induction. Windmill has blades which rotate when it gets an external force. As shown in image, the windmill is same as it. It has a AC generator which produces electrical energy. When winds come across the blades of windmill, they provide a force on it. This make the blades of windmill rotate. When they start rotating, the iron core also rotates because iron core is present in generator and generator is attached to blade in such a way that when blade rotates, the iron cire rotates. Due to electromagnetic induction, this produces electricity in the generator and that energy can be used for different purposes.
-----------------------------------------------------------
→ Reason for the answer :-
We see that the windmill is attached on top of the car. This means that when the car will move then the windmill will get winds so its blades can move. When these blades will move, it will produce electrical energy. As we understood that how windmill works, so similarly the windmill here will produce energy. Now it is given that this energy is used to charge battery. So it can help in charging battery of car. If this happens then car can have more power and its different functions like fast ignition, intensity of head lights, etc. can be increased.
Now some may have a question that the weight of the windmill will provide drag on car so it can reduce its speed, right ?
Well, this is indeed a correct query. Windmill will have some weight and provide drag on car which will increase overall weight of car and thus car will feel more resistance (drag) from air to move freely. We know that streamline shape can overcome air resistance and cars are designed in streamlined shape only. Even the speed of the car which will be increased by charging of battery, will also reduce the contact of tyre of car and road and thus will reduce friction which will not oppose the motion of car.
Thus overall the idea is very successful in improving the efficiency of car. But this can work more better for electric cars only. Thus for electric car, whose whole source of energy is battery this system can provide it constant energy and more energy when there is more wind.
Hence, the answer is yes.

• Electromagnetic Induction : This principle states that due to the motion of the soft armature coil in presence of a magnetic field there is generation of electrical charges in the armature coil.
