In this Physics video lecture in HINDI for class 12 we explained the basic fundamentals of current electricity. The electric current is the flow of charge and it is defined as the rate of flow of charge through any cross section of a region (conductor). The electric current is the ratio of charge flown to the time taken. As the unit of charge, in S.I., is coulomb and that for time is second, the unit of electric current is coulomb/second. This is also known as ampere (A). Hence, we say 1 ampere current is there, if 1 coulomb charge is flown through any cross section in 1 second.
Current in conductors is due to the flow of electrons and the direction of that is called the direction of the conventional current and its opposite direction is considered to be as the direction of the conventional current.
This topic is from Chapter 3 of NCERT 12th Part 1.
