Hi all!
I'm a student in APU University, Cambridge, England. One of my modules is Analogue Electronics, Exams are a few weeks away and i wanted to get an idea of how well I've grasped some of the concepts. We have been given a sheet to work through but have no one to mark it as all lectures are off site.
just wanted to make sure i was on the right track. here's part of it:-
Circuit Diagram - http://www.mwdata.plus.com/diagram.JPG
a) Show that the capacitor C1 has a capacitance of about 13nF.
so C1= 1/(2*Pi*f*Xc)
1/(2*Pi*2000*6000)
=13nF? i think that's ok
b) Calculate the magnitude of the combined impedance of the capacitor C1 in series with R1.
so Z total= Zr1+Zc1?
Z total = 14kOhm?
c) Calculate the current I1 in the circuit.
I1 = Ir1+Ic1?
Ir1=v/r
=3/8000
=3.75mA?
Ic1=3/6000
=5mA?
total = 8.75mA?
d) Calculate the voltage Vc1 across the capacitor C1.
so Vc1= Ic1 * Xc
=0.0005*6000
=3v?
Thank You In Advance.
Jack Wood.
