What is the meaning of the quality-factor q in resonance circuit, what is the amplitude of the q depend on? 4. transient state of series rc circuit (1) what is the three possible state of the series rlc circuit in the transient process (2) when the circuit in the state of damped oscillation, what relationship should the r, l, c meet? what is the changing relationship of the voltage across the capacitor over time? what is the relationship between the frequency and the rlc parameter? which element controls the decay rate of voltage amplitude (time constant)? what equation of the these parameter can describe this process?

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.
