Question

standard tenth first lesson electric circuit plz answer these questions plz guys fast plz if you answer these questions, then mark as brainlist, and I follow you ,don't ask simply, first answers these questions ​.

Answer 1

Explanation:

1. An electric circuit includes a device that gives energy to the charged particles constituting the current, such as a battery or a generator; devices that use current, such as lamps, electric motors, or computers; and the connecting wires or transmission lines.

2. The switch is used to make our break a circuit. that is it is used to open or close a path used For completing a circuit. it's normally connected to the live wire.

3. An electric current is the rate of flow of electric charge past a point or region. An electric current is said to exist when there is a net flow of electric charge through a region. Electric charge is carried by charged particles, so an electric current is a flow of charged particles. The SI unit of electric current is Amperes.

4. The electric current flows from positive terminal to negative terminal. the direction of electric current is opposite to the flow of electrons.

5. There relation is

$a = \frac{dq}{dt}$

Time rate of change of charge

or

charge Q is determined by steady current I flowing for a time t as Q = It.

6. The SI unit of charge is coulombs.

7. 1 coulomb has -6.25*10 ⁻¹⁸ electrons

8. The charge on a single electron is -1.6 x 10⁻¹⁹ Coulomb

9. SI unit of electric current is Amperes.

10. A current of one ampere is one coulomb of charge going past a given point per second:
