Question

1. What does an electric circuit mean?

2. Define the unit of current.

3. Calculate the number of electrons constituting one coulomb of charge.​

Answer 1

Ans. 1-

• An electric circuit means a closed and continuous path through which an electric current flows.

Ans. 2

• The SI unit of current is called Ampere( A ). current flowing through a conductor is said to be 1 ampere , if 1 coulomb of charge flows through it in 1 second.

Ans. 3-

• The charge on an electron is 1.6 × 10‐¹⁹ C. Therefore, the number of electrons in one coulomb is given by
• n = q/e = 1/ 1.6×10‐¹⁹ = 6.25× 10¹⁸.

Answer 2

Answer:

An electrical network is an interconnection of electrical components or a model of such an interconnection, consisting of electrical elements. An electrical circuit is a network consisting of a closed loop, giving a return path for the current.
