Diode Capacitor Circuits I have to ask a question about the capacitor, it would be nice if you helped?
In the full wave rectifier rectifier circuit, the capacitor after the diode, it helps smooth the output current, it only charges with DC and discharge with AC. But the Negative pole of the capacitor is connected to ground, so it will only discharge DC upwards towards the load, great. But wouldn't the output be half a positive wave? since the negative is zero? and wouldn't be in the shape of a sine wave since its AC? How does it have this output form? http://upload.wikimedia.org/wikipedia/commons/thumb/a/a3/RC_Filter.png/400px-RC_Filter.png i don't get it
That is sometimes known as a "reservoir capacitor" if I remember correctly.
Input = sine wave, half the wave positive, half the wave negative. Full-wave rectifier means every "half" of the wave is positive. A reservoir capacitor (aka smoothing capacitor) is placed after the bridge to help smooth the peaks out and provide a more constant DC voltage.
So how does it work? As the voltage rises from 0, the capacitor begins to be "charged". At some point it reaches full charge. As the voltage from the bridge rectifier begins to drop (ie the wave returns towards 0v), the capacitor stops being charged and begins to discharge... supplying the load with positive current. As the wave climbs back towards the peak, the capacitor will stop discharging and go back to being charged.
A capacitor does not discharge AC... it discharges DC only. It reacts to AC differently at different frequencies.... from nearly open to closed.... but it discharges DC only.
This book helps engineers to grasp fundamental theories and design principles by presenting physical and intuitive explanations of switched-capacitor circuits. Numerous circuit examples are discussed and the author emphasizes the most important and fundamental principles involved in implementing state-of-the-art switched-capacitor circuits for analog signal processing and power management applications. Throughout the book, the author presents numerous step-by-step tutorials and gives practical design examples.While some quantitative analysis is necessary to understand underlying concepts, tedious mathematical equations and formal proofs are avoided. An intuitive appreciation for switched-capacitor circuits is achieved.Much of the existing information on contemporary switched-capacitor circuit applications is in the form of applications notes and data sheets for various switched-capacitor ICs. This book compiles such information in a single volume and coherently organizes and structures it.The author has his own website at www.mingliangliu.com

Zener Diode Circuits What is an equivalent part for ct8ph zener diode?
I am working on repairing a circuit and I have found a component that looks like a Zener Diode it is marked CT8PH. I want to replace it because it is damaged but cannot find a replacement part.
Maybe the T is actually a 1 ???
C18PH is a Philips Semiconductor marking for either a BZV85-C18 or a BZX79-C18.
See http://www.datasheetarchive.com/BZV85%2FC15-datasheet.html
They are both 18V zeners. BZV85 is 1.3W, BZX79 is 0.5W.
They are different physical sizes, check out the data sheets to see which is the correct replacement.
The C means 5% voltage tolerance, A18 and B18 are tighter tolerance parts (1% and 2%)

Can i replace the diodes in this distortion circuit with zener 1NT4742A's?
here's the schematic: http://www.instructables.com/files/deriv/F0V/3X4V/FINO74G5/F0V3X4VFINO74G5.MEDIUM.jpg
i know the LED needs to stay, but i cant find the diodes in the schematic anywhere except all electronics and their shipping rate is ridiculous, so i want to know if i can use the 1NT4742A's i already have instead.
1NT4742A is a 12V zener. Since your circuit runs from a 9V supply, the zener action should never come about and these should behave like simpe rectifiers.
The diodes specified in the schematic are also available here:

I'm a DIYer in Electronics but there is a problem I can't solve!
I don't know how is it possible for a circuit to to understand that is the rechargeable battery charged or not. (Without ANY TIMER)
As you know it's not possible to understand if a rechargeable battery is charged or not until you use it.
But i want to design a circuit in order to understand the amount of Energy that it has and charge it automatically if the amount of energy is under the need amount. The type of battery that I use is a car battery and its always in use in the circuit. (it could be used by different situations)
I tried to use transistors and zener diodes to design the circuit but t couldn't help because this kind of circuit is just going to show the amount of Energy at the right time not in a long time!
Any help or suggestion will be highly appreciated!
Thanks
What you want to use is called a Battery Gas Gauge IC. These things are readily available for several rechargeable battery chemistries. You build it in to the charge control circuit. The IC uses a simple characterization table to report the state of the battery based on current in, current out, and time

Resistor Diode Circuit does it matter what side the resistor is on?
If i have a battery a diode and a resistor in a circuit does it matter if the resistor is on the positive or negative side of the battery. I know conventional current goes positive to negative and electrons actually flow the other way. The diode will get the same current no matter where i put the resistor right?
The diode won't get the same current no matter where the resistor goes. If you put the resistor right after the battery it would get different current then if you put it in parallel with the diode or after the diode.
I will assume that when you say diode you mean an LED because a diode resistor circuit would be pretty much useless. Circuit should be a voltage source followed by resistor followed by the LED. Don't forget to correctly calculate the resistor size based on the current that the LED can handle(usually 50mA or less)

a question regarding the voltage drop accross resistors and diodes in parallel ?
if we have a circuit that consists of a diode and a resistor connected in parallel and i applied a dc voltage to the circuit that forward biases the diode ,is the voltage drop across the resistor gonna be the same as the diode ( which is pretty much 0.6 volts ) considering that theyre connected in parallel or theyre gonna be diffrent ?
Voltage drops maintain at 0.6 volt. Diode takes over the control ,it acts like a constant voltage source.
