    Analogue Circuits Question -- AC and DC currents through a coil

    Summary:: . Hi ,so am currently doing homework , and was wondering if anyone could tell me if i have done my calculations correctly ,because am not 100% sure that i have answer to those 2 questions correctly .If i have went somewhere wrong if you could tell me where and how i could fix it...

    Input Resistance of this BJT Amplifier

    Ive tried looking again but couldn't find anything ,but i did find somewhere in my notes which says that RS=RC1=8625 so that means that RS has to be 8625 too right ?

    Input Resistance of this BJT Amplifier

    But if i change the resistor to anything else besides 90k to 96k , ill get smaller or bigger output voltage than i want right.?

    Input Resistance of this BJT Amplifier

    Hi i got a question ,how do i calculate the input resistance ,of the RS resistor ,so i would get half of the voltage of the voltage source (500mA) .I've created the circuit in ltspice and found out that its around 95K ohms to get 250mA,but how would i calculate it . Ive also attached my...

    Cutoff frequency for this RLC circuit

    when i search it i get 1/2*pi*L*C formula , and when i use it i get answer or 8kHz but the simulation is showing 11.1kHz
