- The current in a 62 mH inductor changes with time as I = bt- at. With a = 6 A/s and b = the magnitude of the induced emf, E, at 6 A/s, find t = 0.7 s. Answer in units of V. At what time is the emf zero?A physics student observes that the current in a coil of conducting wire goes from i, = 0.200 A to i, = 1.50 A in a time interval of At = 0.350 s. Assuming the coil's inductance is L = 5.00 mH, what is the magnitude of the average induced emf (in mV) in the coil for this time interval?A loop of wire has a self-inductance of 5.5 mH. You pass a current of 9.0 Amps though the loop, and then drop the current to 0 at a contastant rate over 3.5 seconds. What is the EMF generated?
- Two coils have a mutual inductance M = 0.0311 H, while the first coil has self- inductance L₁ = 0.0251 H. If the current through the first coil is changing at a rate di₁/dt = 2.32 A/s and the current through the second coil is changing at a rate di2/dt = 4.09 A/s, what is the magnitude of the EMF in the first loop? V INplease use these description Read the section for moreinformation. The unit ofinductance is the “Henry,”symbolized “H”EMF = Electromotive force= VoltageAnswer must includecorrect units.A 25-turn ideal solenoid has an inductance of (4.19x10^-3) H. To generate an EMF of (1.5x10^0) V what should be the rate of change of the current? Express your result as the magnitude in A/s.
