Question

1) A solenoid of radius 2.30 cm has 540 turns and a length of 25.0 cm.

(a) Find its inductance.
Answer must be in mH

(b) Find the rate at which current must change through it to produce an emf of 50.0 mV. (Enter the magnitude.)
Answer must be in A/s

6) An AC source operating at a frequency of 200 Hz has a maximum output voltage of 3.00 V. What is the smallest inductor that can be connected across the source and the rms current remain less than 1.30 mA? (Enter the inductance in H.)

Answer must be in H
