Question

What is electric charge .

Answer 1

Answer:

Electric Charge

Explanation:

Electric Charge:

Electric charge is the property associated with matter due to which it produces and experiences electrical and magnetic effects. It is known that every atom is electrically neutral, containing as many electrons as the number of protons in the nucleus. Charged particles can be created by disturbing the neutrality of an atom. Loss of electrons gives positive charge (as no of proton is greater than no of electron) and gain of electrons gives negative charge ( as number of electron is greater than no of proton) to a particle. When an object is negatively charged, it gains electrons and therefore its mass increases negligibly. Similarly, on charging, a body with positive electricity its mass decreases. Change in the mass of the object is equal to n x m where n is number of electrons transferred and m is the mass of electron.

Properties of charge:

Charge is transferable.

Charge is always associated with mass.

Charge is conserved.

Answer 2

Electric charge is defined below :

- When subatomic particles are placed in an electromagnetic field then these particles experience force which is caused due to electric charge.

- Further charges are classified as positive and negative charges and the charge is transferred via protons and electrons.

- Also an electric charge can only be exchanged and it cannot be created.

- Electric charge occurs in discrete amount.

- The S.I unit of electric charge is Coloumb.
