Discharging Through Heating

When an object has more protons than electrons, the object has a positive charge. But when the object has more electrons than protons, the object has a negative charge. Through heating, the protons and electrons of an atom could be even out again.

Grounding - the Removal of a Charge

Grounding is a method used to remove the excess electrons from an object to make it neutral (discharged), by connecting an object to the earth by using a wire or other conductor  material(metal). So the electrons are moving down to earth straight away. If an object has a positive charge so the electron from the earth move upward to neutrals excess positive charge object  to become neutral (substance).  This method that we use to avoid from electric shock case  that will happen to us when we touch an object that’s not neutral (contain excess electric charge),  and also this method  will safe our electric equipment damage by electric shock. It will make our electric equipment will have longer age to use.

Charging by Induction

 Charging through induction is the process where an item is charged without touching each other. This could happen by taking a negatively charged item and moving it to one of 2 sphere balls on an insulating stand(this is necessary because the ground neutralizes charges), the neutral charged sphere will move to the other charged sphere due to the negative charge repelling from the balloon's negative charge. The negative charge of the sphere will move to the other sphere, the two spheres will then become opposite charges. 

The same thing happens when the balloon is positively charged but instead of sphere 1 losing its negative charge, its sphere 2 who loses it. Another way of explaining induction is when a magnet is pushed in and out of a metal coil, the metal coil will be charged and can be hooked up to a light. The speed of the push and pull, the magnet's power and the coil's number of spiral play a big role in this. The more of the above is present, the more electricity will generate.
