ELECTRICITY CLASS 10 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].
