Question

define electric current of chapter 11th explanation​

Answer 1

Answer:

Electric current can simply be defined as the rate of flow of electric charge.

Or, electric current is the amount of charge flowing through a particular area in unit time . The SI unit of electric current is ampere which was named after the scientist Andre Marie Ampere.

I= $\frac{Q}{T}$          Where, I = electric current

                            Q= Electric charge

                            T= time taken.

Hope it helps you !!!!!!!!

Explanation:

Answer 2

Answer:

• An electric current is a flow of particles (electrons) flowing through wires and components.
• It is the rate of flow of charge. If the electric charge flows through a conductor, we say that there is an electric current in the conductor.
• In the circuits using metallic wires, electrons constitute a flow of charges.

Electric Current Formula and Unit

• The conventional direction of electric current is taken as opposed to the direction of flow of electrons.
• If a charge Q flows through the cross-section of a conductor in time t, the current I then I=Q/t.
• The S.I unit of charge is coulomb and measurement of electric current happens in units of coulomb per second which is ‘ampere’.
• The current flows from the negative terminal to the positive terminal of the cell.
