Answer 1

Hey Mate ✌✌

Here is your answer...

_________________

When a matter is placed in an electromagnetic field, force experienced by the matter is called as the charge.

It is the one of the physical properties of matter. SI unit of charge or electrical charge or electrostatic charge is Coulomb or C.

The rate of flow of charges is called as current.

Answer 2

Answer:

Charge -

→ Charge is a fundamental particle in an atom. It may be positive or negative.

• Positive charge - These are made of sub atomic particle proton.

• Negative charge - These are made of negative sub atomic particle electron.

→ Like charges repel each other.

→ Unlike charges attract each other.

→ Coulomb (C) is the SI unit of charge.

→ The SI unit of 1 coulomb is equivalent to the charge containing 6.25 × 10^-18 .

→ 1 coulomb charge = charge present on approx 6 × 10^18 electrons.

→ Charge on 1 electron = negative charge of 1.6 × 10^-19 C.

i.e Q = ne

Where, Q = charge (total)

n = number of electrons

e = charge on 1 electron.
