A 521-turn solenoid has a radius of 7.00 mm and an overall length of 15.0 cm. (a) What is its inductance? mH (b) If the solenoid is connected in series with a 2.50- resistor and a battery, what is the time constant of the circuit? ms

An RLC circuit consists of a 3.59 £2 resistor, a 3.32 µF capacitor, and a 32.1 mH inductor. Initially, the voltage across the capacitor is 8.63 V, and no current is flowing in the circuit. What is the magnitude of the charge on the capacitor after 0.0787 s? It is acceptable to let @' = @. i ! nC

Tarik winds a small paper tube uniformly with 173 turns of thin wire to form a solenoid. The tube's diameter is 7.95 mm and its length is 2.07 cm. What is the inductance, in microhenrys, of Tarik's solenoid? inductance: µH

Your RL circuit has a characteristic time constant of 21.5 ns, and a resistance of 5.40 MΩ. A. What is the inductance (in H) of the circuit? B. What resistance (in MΩ) should you use (instead of the 5.40 MΩ resistor) to obtain a 1.00 ns time constant, perhaps needed for quick response in an oscilloscope?
