Please Correct me on this i think i am wrong on these charts
this is not my homework


Capacitor Chart:

AC function generator hooked up to a Capacitor
(Capacitors in AC circuits)

Frequency: Goes Up it increases
a.) Current: Goes Up it increases
b.) Rate of Chage: Increases
c.) Capacitive Reactance: decreases
d.) Phase= increases
e.) Voltage (Vc)= Goes down it decrease



Inductor Chart:

AC function generator hooked up to a inductor
(inductors in AC circuits)

Freqency: Goes up it increases
a.) Current: decreases
b.) Inductive reactance: increases
c.) Phase: decreases
d.) Voltage (V little L): goes up it increases


Series RC circuit Chart:

AC function generator hooked up to a Series RC circuit/network

Basic ( RC Lag circuit chart):
Frequency: Goes up it increases
a.) Current: goes up it increases
b.) Capacitve reactance : goes up it increases
c.) Resistors voltage (Vr) : goes up it increases
d.) Capacitors voltage (Vc): goes down it decreases
e.) Phase (lag) angle: goes down it Decreases
f.) Impedance (Z) : goes down it decreases
g.) Vout: goes up it increases


Series RL circuit Chart:

AC function generator hooked up to a Series RC circuit/network

Basic ( RL Lag cicuit chart)
Freqency: goes up it increases
a.) Current: goes down it decreases
b.) Resistors voltage (Vr): goes down it decreases
c.) Inductors voltage (V little L): goes down it decreases
d.) phase (lag) angle: goes up it increases
e.) Impedance (Z) : goes down it decreases
f.) Vout: goes down it decreases
g.) Inductive reactance: goes down it decreases

Engineers are lazy and they dont use charts.

Im pretty sure anyone electronics novice have done exercises where they resolve a network of resistors to find the net resistance. Well, just do the same with a network of impedances to get net impedance.

Z(resistor) = R
Z(capacitor) = 1/jwC
Z(inductor) = jwL

Note impedance is normally a function of w=2*pi*f (signal frequency).

Since by definition, Z=V/I, by knowing impedance, you can easily calculate currents,voltage,phases,magnitudes or whatever you want, by just substituting the input frequency. DC analysis is simply freq=0.

I think you'll find the opposite (the chart part :lol has more truth in it. When you see an engineer not doing anything, most likely he/she is contemplating some great solutions to a minor problem.

In the engineering field there are far too many charts and tables and all engineers loves them because no one would like to calculate anything again from first principle.
