inductor: € == dI dt Lenz's Law: The induced EMF will fight the change in current through an - Ld where L is called the "inductance". The MKS units for inductance are Henry's (H). Note that L is greater than zero by definition. The minus sign tells you which direction the induced current will point. A) An induced emf of 20 mV is measured across a coil of 50 closely wound turns while the current through it increases uniformly from 0.0 to 5.0 A in 0.10 s. What is the self-inductance of the coil? Answer: L = 4.0x10-4 H

Please Asap

please use these description Read the section for moreinformation. The unit ofinductance is the “Henry,”symbolized “H”EMF = Electromotive force= VoltageAnswer must includecorrect units.

The current in a coil decreases from 9.0 A to 5.5 A in 0.30 s. If the average emf induced in the coil is 25 mV, what is the self-inductance of the coil?

In the circuit shown in the Figure with 3.0 mH for the inductance and 6.0 uF for the capacitance, S1 has been closed for a long enough time so that the current reads a steady 3.50 A. Suddenly, S2 is closed and S1 is opened at the same instant. What is the maximum charge that the capacitor will receive?  What is the current in the inductor at this time? At an instant when the charge on the capacitor is 0.1 mC, what is the current in the inductor? At an instant when the charge on the capacitor is 0.1 mC, what is the rate at which the current in the inductor is changing?

Say we have an inductor with an inductance of 2.5 H.  How fast does the current through it change when the voltage across it is 10 V?

Coil A is a large 300 turn circular coil of radius 77 cm. Circular coil B has 390 turns, a radius of 5 cm and is located L=99 cm from coil A along the same axis. The planes of the two coils are parallel. A) Find the approximate mutual inductance of this pair of coils.     for my answer I got 3.527E-10 H which was wrong B) If the current in coil A varies with time according to I=3t3−8t2−1, where I is in amps and t is in s, find the magnitude of the EMF induced in coil B at time t=2 s.

What is the inductance of a coil in which the average emf induced is  20.0 mV when the current in the coil is increased from 3.50 A to 7.70 A in 0.330 s?

An inductor has an inductance of 0.120 mH. Calculate the number of turns per unit length (meter) of this inductor if it has a total of 719 turns in it.
