30. Induction and Inductance

Inductance of a Solenoid. (b) A metallic laboratory spring is typically 5.00 cm long and 0.150 cm in diameter and has 50 coils. If you connect such a spring in an electric circuit, how much self-inductance must you include for it if you model it as an ideal solenoid?

An L-R-C series circuit has L = 0.450 H, C = 2.50 * 10^-5 F, and resistance R. (b) What value must R have to give a 5.0% decrease in angular frequency compared to the value calculated in part (a)?

An L-R-C series circuit has L = 0.450 H, C = 2.50 * 10^-5 F, and resistance R. (a) What is the angular frequency of the circuit when R = 0?

An L-R-C series circuit has L = 0.600 H and C = 3.00 mF. (b) What value of R gives critical damping?
