Electric Car

Electric car is a fun science experiment which uses electrical items like Motor, Battery, Bread board, Resistor and LED. The electric car runs on electricity!

The car consists of a motor which rotates and you can have your own eco-friendly car!

What to Do!

  1. Place the motor inside the steel clamp.
  2. Now place the motor along with the clamp on the two holes in the bread board and insert the screws.
  3. Attach the screws with nuts at the back and also attach the fan to the shaft of the motor.
  4. Move the motor away from the board and make sure its movement is not obstructed and the fan moves freely.
  5. Fix the motor position at that point and remove the fan.
  6. Tighten the screws using a screw driver.
  7. Now mark positive and negative at the front end of the bread board.
  8. Then insert the negative terminal of the LED in A3 and the positive terminal in the first terminal of the positive line.
  9. Similarly, insert the other LED. Insert the positive terminal in J3 and the negative terminal in the first terminal of the negative line.
  10. Measure the red wire to length of 6cm and cut it using the wire cutter.
  11. Similarly, cut a length of black wire measuring 6cm and a red wire measuring 3cm.
  12. Using a wire stripper, strip the ends of all the wires.
  13. Now bend all the wires in the perpendicular direction using a forceps.
  14. Now insert one end of the black wire in the negative line adjacent to the LED terminal and insert the other end of the wire next to the negative terminal of the other LED.
  15. Now insert one end of the red wire in the positive line adjacent to the LED terminal and insert the other end of the wire next to the positive terminal of the other LED.
  16. Cut a part (2cm) of double sided tape and stick it on the battery.
  17. Remove the tape and affix the battery between the LEDs and make sure the rear end is about 1 cm outside the bread board.
  18. Connect the crocodile clips to the motor and insert the wires into the straw and bend it slightly.
  19. Mark a (+), (-) and (- -) and connect the black wire to the (-) terminal.
  20. Now take the snap connector and insert the red wire in D28 and insert the switch between B27-B29 & D27-D29
  21. Insert the black wire of the snap connector with the resistor.
  22. Insert the short red wire in A29 and in the positive line and insert the red wire coming from the motor also in the positive line.
  23. Connect the snap connector with the battery and your connections are done.
  24. Now measure 12 cm from the pointy end of the skewer and cut the skewers at the 12 cm mark and using a paper cutter, trim the other end of the skewers to make it pointy too. Repeat this for all ends for both the skewers.
  25. Take out the two tubes of Araldite.Pour small and equal amounts from each tube and mix it with the skewer and make a paste.
  26. Apply the paste on top of the pointy skewers and insert and attach the wheel. Repeat this for all the wheels and your axles are ready!
  27. Place the axles in such a way that it is about 4 cm away from the edge of the bread board and attach the wheels with electrical tape.
  28. Attach the fan and press the switch to see your car move!

Working Principle of Electrical Car :

The principle behind this experiment is Electricity and Magnetism. The most important part of the car is the Electric Motor. The Electric Motor runs on electricity, it rotates and it has both electricity and a magnet. An Electric motor is used in many machines such as fans, mixers and washing machines.

The Electric Car uses a fan that gushes out wind from behind the car and produces a force called ‘Action’ in the direction opposite to the motion. And according to the 3rd Law of Newton, a force called ‘Reaction’ is produced in the direction of the motion which produces the motion in the car.
