Instances of the types of charges are subatomic units or the elements of matter:
- Protons are positively charged
- Electrons are negatively charged
- Neutrons have zero charge
When two currents come in contact at a place, in the case of an electric current, the resultant current of these will come out to be an algebraic sum. It will not be a vector sum. It holds magnitude and direction. Nevertheless, it still remains a scalar quantity.
The definition of a Coloumb is represented mathematically as
In the equation, Q is the electric charge, I is the electric current, and t is the time.
|Definition||Electric Charge is the characteristic of subatomic elements that makes them undergo a force when positioned in an electric and magnetic field.|
|Formula||Q = I.t|
|Other Units||Faraday, Ampere-Hour|
There are some properties of Electric charge. These include the following-
- Conservation of Electric charge
- Additivity of Electric charge
- Quantization of Electric charge
When an item has a positive charge, it implies that it has more protons than electrons. When there is an identification number of positive and negative charges, the positive and negative charges would cancel each other, and the item would become out of charge, i.e., neutral.
When an item is negatively charged, it implies it contains more electrons than protons.
Coulomb’s Law states that-
Coulomb’s Law is represented as the following-
An item with no charge can be charged in three different ways. These are as follows-
- Charging by conduction
- Charging by friction
- Charging by induction
Charging by Conduction
The method of supplying charge to an uncharged item by bringing it in contact with a charged item is referred to as Charging by conduction. The charged conductor has an uneven number of positively charged protons and negatively charged Electrons. Therefore, when an object with no charge is brought in contact with the same, it loses electrons to balance itself.
Charging by Friction
When two items are rubbed with each other, the transfer of charge occurs. One of the items displaces electrons. On the other hand, the other item acquires electrons. The object that loses electrons turns positive, while the object that attains electrons, turns negative. Both of the items get charged because of friction. This approach of charging is frequently referred to as electrification by friction.
Charging by Induction
The process of supplying charge to an uncharged item by bringing it in contact with a charged conductor despite any physical contact is referred to as Charging by induction.
