What is the characteristic time constant of a 23.3 mH inductor that has a resistance of 4.09 Ω?               ms (b) If it is connected to a 12.0 V battery, what is the current after 12.5 ms?                A

In an RLC circuit, the resistance R does NOT change with frequency. Why would VR change with frequency(consider other factors in the circuit).

A constant voltage of 11.00 V has been observed over a certain time interval across a 2.30 H inductor. The current through the inductor, measured as 1.00 A at the beginning of the time interval, was observed to increase at a constant rate to a value of 8.00 A at the end of the time interval. How long was this time interval?

Calculate the resistance in an RL circuit in which L= 0.04 H and the current increases to 90% of its final value in 3.00 ms.

In a standard RLC circuit that we are looking at R = 0.075 Ω , L = 1.2 H and C = 1.6 F.  The initial charge carries by the capacitor is Q0 = 0.045 C.  The switch is closed at time t = 0.   Calculate the value of Q, in coulombs, at time t = 1s.
