Consider the circuit shown in the figure below. Take = 6.00 V, L = 12 mH, and R = 5 Q. Shown in the figure below. T S R (a) What is the inductive time constant of the circuit? (b) Calculate the current in the circuit 250 µs after the switch is closed. (c) What is the value of the final steady-state current? (d) How long does it take the current to reach 70.0% of its maximum value? +

I am doing physics homework and am stuck on this part! Help would be great, thank you!

PART (1) Assume capacitor is fully charged when switch is at position 'a' for about 10 minutes. The switch is changed to position 'b' at t= 0. What is the current in the circuit immediately after the switch is closed? Assume after some time, the current in the circuit is 80.0 mA when the switch is at position 'b'. Can you find, what will be that time? 9.0 V 부 Paragraph a itur b 1.0 με PART (II) Assume a magnetic field of 5.2 T present inside the cyclotron. An electron enters the cyclotron with speed of 2.0 x 107 m/s. What is the radius of the electron's orbit just before they exit from the cyclotron. BI U A/ 10 Ω E✓ E GO + v

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?
