Alternating Current Class 12 Notes Chapter 7

1. Alternating Current (AC) It is the current which varies in both magnitude as well as direction alternatively and periodically. I = I0 sin ωt or I = I0 cosωt where, I0 = peak value or maximum value of AC. 2. Effective Value or rms Value of AC It is defined as the...

Electromagnetic Induction Class 12 Notes Chapter 6

1. Magnetic Flux The magnetic flux linked with any surface is equal to total number of magnetic lines of force passing normally through it. It is a scalar quantity. 2. The phenomenon of generation of current or emf by changing the magnetic flux is known as...

Magnetism And Matter Class 12 Notes Chapter 5

1. The magnetic dipole moment of a magnetic dipole is given by M = m × 2I where, m is pole strength and 2I is dipole length directed from S to N. The SI unit of magnetic dipole moment is A-m2 or J/T. It is a vector quantity and its direction is from South pole to...
