flow of charge

Electrical current is the flow of charged particles. The electric current flows through a wire the same way as how water moves in a river. The electricity is nothing but the flow of electrons. What does the circuit diagram signify?

The rate of flow of charge in a circuit is called electric current. In other words, it is the amount of charge flowing per second. It is denoted by the letter I. If Q is the charge which is flowing through a conductor in time t, then current is given by i = Q/t Unit of current: The S.I unit of current is ampere and it is denoted by the letter 'A'. The S.I unit of Q is coulomb and that oft is second. Thus, the S.I unit of electric current is ("1 coulomb")/("1 second") = 1A If there is a current of 10 amperes in a circuit for 10 minutes, what quantity of electric charge flows in through the circuit?

Thus, the S.I unit of electric current is ("1 coulomb")/("1 second") = 1A How much time is required for 10 coulombs of charge to flow past a point if the rate of flow (current) is 2 amperes?

A and B are two isolated conductors (that means they are placed at a large distance from each other). When they are joined by a conducting wire : (i) Find out final charges on A and B ? (ii) Find out heat produced during the process of flow of charges. (iii) Find out common potential after joining the conductors by conducting wires ?

Electric current in a wire is time rate of flow of charge. The charge in coulombs that passes through a wire after t seconds is given by the function q(t)=t^(2)-2t^(2)+5t+2 . Determine the average current (in coulmbe per second) during the first two seconds.

The rate of flow of charge in a circuit is called electric current. In other words, it is the amount of charge flowing per second. It is denoted by the letter I.

The S.I unit of Q is coulomb and that oft is second. Thus, the S.I unit of electric current is ("1coulomb")/("1 second") = 1A How much current must there be in a circuit if 100 coulombs flow past a point in the circuit in 4 seconds?

Assertion (A) : Putting p-type semiconductor slabs directly in physical contact can not form p-n junction Reason ( R) : The roughness at contact will be much more than inter atomic crystal spacing (= 2 Å to 3 Å) and continuous flow of charge carriers is not possible.
