A self-induced emf in a solenoid of inductance L changes in time as ε = ε0e-kt. Assuming the charge is finite, find the total charge that passes a point in the wire of the solenoid.
A solenoid has an inductance L- 2.60 H. The time-dependent induced emf in the solenoid is given by the expression & Ege-bt, where &o- 2.55 mV and the constant b 1.70 s¹. Consider
the time interval measured from t= 0 to a very long time later (which you can approximate as an infinite amount f time). What is the total charge that flows through a point in the solenoid during
this time interval?
