FAQs on Class 12 Physics Notes for All Chapters

1. What is Kirchhoff’s first law of electricity in Class 12th Physics Notes?

Kirchhoff’s first law, also known as Kirchhoff’s junction law supports the law of conservation of charge and It states that in a closed circuit, the algebraic sum of the currents meeting at a point is zero i.e Σi = 0. The law also states:

Current cannot be stored at the meeting point or junction.

No junction in a circuit can act as a sink or source of charge.

2. What is a solenoid in Class 12 Physics Notes?

A long insulating wire-wound closely in the shape of a helix forms a solenoid. The length of a solenoid wire is considerable compared to its diameter. Properties and features of a solenoid are:

When current passes through a solenoid, it creates an almost uniform magnetic field inside.

The direction of the magnetic field is the same as that of the current inside it.

Solenoids are widely used in switches as they can convert an electric current into mechanical action.

The density of turns and the strength of the current solenoid determines the magnetic field inside it.

Even a small solenoid can exert a force equal to few newtons.

A solenoid is like a permanent magnet, but it can be reversed and turned on/off at will.
