please show step by step how to do d through h, I will upvote. thank you
A 62.0m length of copper wire is wound to form solenoid of radius 2.1cm. The wire has radius 0.53mm and resistivity 1.7E-8. I need to know the self inductance of the solenoid, the time constant if connected to battery of emf 6V and Rint of 350 mOhms, the max current, how long to reach 99.9% of Imax, and the maximum energy stored in the inductor.
(c) How long is the resulting solenoid? 0.498 m (d) What is the self-inductance of the solenoid? 0.0062 X Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. mH (e) If the solenoid is attached to a battery with an emf of 6.0 V and internal resistance of 350 m, compute the time constant of the circuit. ms (f) What is the maximum current attained? X Your response differs from the correct answer by more than 10%. Double check your calculations. A (g) How long would it take to reach 99.9% of its maximum current? ms (h) What maximum energy is stored in the inductor? m]
