When the current changes from +2 A to - 2 A in 0.05s, and EMF of 8V is inducted in a coil. The coefficient of self-induction of the coil is
Question
Solution 1
The coefficient of self-induction, also known as inductance (L), can be calculated using Faraday's law of electromagnetic induction. The formula is:
L = - (ΔV / ΔI) * Δt
where:
- ΔV is the change in voltage (EMF),
- ΔI is the change in current, and
- Δt is the change in time.
Given:
- ΔV = 8 V,
