 Q:what is the relationship between voltage and current for resistor,capacitor and inductor?
 First of all, remember that the question only has meaning if you are discussing an AC circuit being driven by a sine wave (not a square wave or any other waveshape) In a resistor, the current flowing through it is in phase with the voltage applied across it. In a capacitor, the current flowing through it is π/2 Radians (or 90°) ahead of the voltage applied across it. (This is also called 'leading' the voltage) In an inductor, the current flowing through it is π/2 Radians (or 90°) behind the voltage applied across it. (This is also called 'lagging' the voltage) In a resistive circuit, it is the resistance value which limits the current flow. In an inductive or capacitive circuit, it is a thing called the 'reactance' of the capacitor (capacitive reactance) or the inductor (inductive reactance). Reactance is different from resistance in two very important ways. First, reactance is frequency dependent. That is, it changes as the frequency of the applied foltage changes. And it causes a π/2 Radian (or 90°) phase shift in the current flowing through the circuit. These are all very important things for you to know and know well. And I'm sure that your teacher will explain them during the class. Doug

 Q:Voltage Drop Across An Inductor?
 Your book is not very good. I'm not sure what it means by rise in time. If the current is increasing swiftly in shorter intervals of time then the voltage increases dramatically. You are correct in your thinking. lim dt0 (as dilarge values) di/dt infinity
 Q:How much energy is stored in the inductor?
 U Potential energy R Resistance 6.7ohms I current V/R (10.5V/6.7ohms) 1.57A L inductance 265mH .265H U (.5)LI^2 (given formula in any physics text book) U (.5)*(.265H)*(1.57A)^2 .33 J
 Q:In an AC circuit containing a resistor,capacitor & an inductor,impedence replaces the DC concept of resistance?
 Impedance can have both resistive and either inductive or capacitive components (in electrical engineeringspeak, we give the impedance as a complex number for a given frequency).
 Q:Inductor time constraints question?
 Please convert your 10 mH to 10000H and do your calculation. The time constant is L/R 10 sec. The time constant gives you 63.2 percent of current. See the formula I (E/R)*(1  Є^Rt/L). Є^Rt/L always gives you a positive result whatever the R,t,L is. So (1  Є^Rt/L) always less than one. That is why the maximum value of current theoretically never been reach unless t is very long to make Є^Rt/L minimum.

 Q:the current through an inductor?
 No current flows through the inductor at t0, because iL (1/L)*integ[V, dt] and for constant voltage (it is constant at the instant it is applied), iL (1/L)*V*t, then for t 0, iL 0.
 Q:Assume that we set up a circuit with a resistor, a capacitor and an inductor in serial.?
 The current is a maximum at resonance, when the reactances of the cap and the inductor cancel out. But the current will not exceed the value you would get with the resistor alone. resonance frequency: f 1/(2π√(LC)) .
 Q:when current passes through inductor emf is induced across it ,if this inductor is further connected to loop?
 An inductive coupling link/loop can be used with a loop antenna. This works in the same way as a transformer, with the inductive link as the primary (for transmitting), but at the particular radio frequency. A loop antenna often represents some sort of resonant circuit, and this can be combined with the inductive link coupling to match the antenna impedance to the transmission line and transmitter impedances. With other types of antenna an inductor and/or capacitor arrangement (an LC network) may be used for matching the antenna impedance to the lines. The actual values and conficuration depends on the specific antenna. For example, teh model of a vertical quarter wave antenna is a small capacitor in series with the radiation resistance. By adding a series inductor the capacitance can be made to resonate, maximising the current in the radiation resistance.
