The current in a coil decreases from 30 amp to 10 amp in 0.2 sec if the self inductance of coil is 4 Henry. What is the induced emf in volts?
Question
Solution 1
To find the induced emf, we can use Faraday's law of electromagnetic induction, which states that the induced emf is equal to the rate of change of magnetic flux. In mathematical terms, it is given by:
E = -L * (ΔI/Δt)
where: E is the induced emf, L is the self-inductance of the coil, ΔI is the ch Knowee AI is a powerful AI-powered study tool designed to help you to solve study problem.
