What is the condition for resonance?
Condition for resonance:
The condition of frequency of the oscillatory circuit is equal to frequency of the vibrating rod as:
1/(2 Π (√LC)) = 1/(2l (√E/ρ))
Here, l is the length of the rod.
E is the young's modulus of material of rod.
ρ is the density of material of the rod.
Their resistivity is very low and temperature coefficient of resistance is not constant. These are materials with unfilled or overlapping energy bands. Current carriers here are fr
How to calculate change in entropy.
LENZ’S LAW A change of flux in a closed circuit induces an emf and sets up a current. The direction of this current is such that its magnetic field tends to oppose the c
