Question

I need assistance on 2.1 and both parts of question 2.2

The basic geometric shape of inductors is the same as a solenoid (a coil of many loops). Such inductors are often used in a circuit through which a current I changes with time t, i e. I = I (t). Time-dependent current I (t) can produce a potential difference across an inductor V_L = -L Delta I/Delta t, where L is the inductance of the inductor. The inductance L generally depends on the geometric size (shape) of the inductor, and has unit of Henry [H]. Making use of the time dependence of V_L (or I), you can control physical phenomena of AC circuits (such as; electric resonance of an AC circuit (Fig.2) and low pass filtering of a current (Fig.3(b)) as shown in the manual), which you could not see in DC circuits. Briefly explain about the reactances and the impedance of an AC circuit. Explain the condition for a resonance of a RCL series circuit connected to an A power source. Calculate the resonance frequency of the RCL series circuit composed of a 10 mu F capacitor, a 10mH inductor, and a 1k Ohm resistor.
