Electrical Circuit and Self Inductance? With a battery emf of 13.6 V in the RL circuit ( R=0.710 ? and L= 78.0 mH), what is the self-induced emf when the switch has just been closed on a? What is the self-induced emf after two L/R time constants have passed? In units of the time constant, after how much time will the self-induced emf be just one-half of the battery emf?
3. Calculate the self-induced emf in the solenoid of inductance L = 0.181 mH, if the current decreases at the rate of 50.0 A/s.
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).

what does neuroscience say about self and how does this create the "ego" trick?
The inductance of a closely wound coil is such that an emf of 4.71 mV is induced when the current changes at the rate of 3.1 A/s. A steady current of 3.87 A produces a magnetic flux of 43.9 mu Wb through each turn. (a) Calculate the inductance of the coil. (b) How many turns does the coil have? (a) Number Units (b) Number Units
