For an inductor of inductance, L, the relationship between the back emf E_back and the time rate of change for a change of current through it is given by:
E_back = -L (dI/dt)
Question: Suppose that for a given inductor I(t)=2.5 sin(5.0t) and E_back is -0.25 cos (5.0t), find the inductance L in henries (H).
Please show your answer step by step (I am a first year physics student).

To leam about self-inductance from the example of a long solenoid.
Learning Goal:To leam about self-inductance from the example of a long solenoid.To explain self-inductance, it is helpful to consider the specific example of a long solervid, as shown in the figure. This solenoid has only one winding, and so the EMF induced by its changing current appoars across the solenoid itsel. This contrasts with mutual inductance, where this voltege appears across a second coil wound on the same cylincter as the lirst.Part ASuppose that the current in the solenoid is...

An LR circuit includes a resistor of resistance R, an inductor of inductance L and a battery of emf E = 10 V. At time t = 0 the current in the circuit is I = 0. At time t = 6.1 ms the current is I = 0.66 A. Assume R = 100ohms, find L.
