How does a generator convert mechanical energy into electrical energy?

Explanation:

A generator is a device which converts mechanical energy into electrical energy.

It is based on the principle of electromagnetic induction.

The armature coil of the generator rotates by using the mechanical energy. As the armature of the generator rotates, the magnetic flux linked with the coil changes. When the magnetic flux linked with the coil changes, an induced emf is developed.

the magnitude of the induced emf is equal to the rate of change of magnetic flux.

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day
