The current in a 10 mH inductor is given by `I = (10t^2 - 5t + 10)`. Find emf across the ends of the inductance coil at t = 1 sec.

The flux linked with a coil at any instant t is psi = (5t^2 - 10t + 7) weber. Calculate the induced emf across the coil at t = 2 sec

The current through a 1mH inductor changes from 5 ampere to 10 ampere in 1 millisecond. Find the emf induced.

A charge of Q coulomb passes through any cross-section of the conductor is given by Q = 3t^2 - 2t + 10 where Q is in coloumb and t in second. Find the current flowing through the conductor at the time instant , t = 2 seconds.

The current flowig through an inductor drops from 10A to 2A in 2m sec. If the self inductance of the coil is 10mH, find the emf induced across the ends of the inductor.
