Q.) What is electricity? 

Ans:- Electricity is the form of energy. 

Or

➡️Electricity is the flow of electrons. 

➡️Electricity is the flow of electrical power or charge. 

Q.) What is charge? 

Ans:- That property of matter due to which they exert electrical forces on each other, called charge. 

➡️It is an intrinsic property. 

➡️Intrinsic :- It can't be removed. 

➡️Charge at rest :- produces only electrical effect. 

➡️Charge in motion :- produces both (i) Electrical and (ii) Magnetic effects. 

Q) What is an electric charge? Is it a scalar or vector quantity? Give S.I . unit. 

Ans:- Electric charge is a physical quantity which causes electric force in matter. 

➡️Charge is denoted by Q/q. 

➡️The electric charges at rest are known as static charge. 

➡️Charge is a scalar* quantity.

➡️SI unit of charge is coulomb (C). 

➡️Dimensional formula of charge is [AT].
