What is the difference between a zener diode and a rectifier diode?
478814
Both are similar devices in that they only conduct current in one direction and if you apply a voltage in the non-conducting direction and gradually increase it, for a high enough voltage it will suddenly start to conduct.   But zener diodes are designed to break down at an accurately-known voltage, specified by the manufacturer, so they're designed to be used as voltage regulators.   You can buy them in a wide range of breakdown voltage.   A rectifier diode is designed simply to convert AC to DC.

The transistor is a solid state semiconductor device that can be used for amplification, switching, voltage stabilization, signal modulation and many other functions. It allows a variable current, from an external source, to flow between two of its terminals depending on the smaller voltage or current applied to a third terminal. Transistors are made either as separate components or as part of an integrated circuit.\n\nA semiconductor is a material with an electrical conductivity that is intermediate between that of an insulator and a conductor.\n\nThe p-n junction diode is a device made from a p-n junction. At the junction of a p-type and an n-type semiconductor there forms a region called the depletion zone which blocks current conduction from the n-type region to the p-type region, but allows current to conduct from the p-type region to the n-type region. Thus when the device is forward biased, with the p-side at higher electric potential, the diode conducts current easily; but the current is very small when the diode is reverse biased.\nExposing a semiconductor to light can generate electron-hole pairs, which increases the number of free carriers and its conductivity. Diodes optimized to take advantage of this phenomenon are known as photodiodes. Compound semiconductor diodes can also be used to generate light, as in light-emitting diodes and laser diodes.

A Vaccum tube diode uses the applied voltage to create thermionic emmisions which results in sending electrons from the cathode filament to the Anode plate. This was replaced by a Semiconductor diode, which  depends on the applied electric voltage to break the barrier formed at the p-n junction. \n\nA triode is similar to a Vaccum tube diode, but gets a helping hand by concentrating the electrons using a Grid. This allows a small change to the Grid voltage to vastly increase the flow of electrons between Cathode and Anode, thus allowing Amplification.\n\nTriode Tubes were later replaced by a Semiconductor Transistors, Field effect Transistors and Bipolar Junction Transistors. However, even today, Tubes can work at far more higher voltage ranges than a semiconductor device.

yeah you can use a switch (voltage switch) or if you can use binary logic, need to know how much voltage/current you are dealing with

A bridge rectifier makes use of four diodes in a bridge arrangement to achieve full-wave rectification ... component bridges where the diode bridge is wired internally ...

a ditisbution transformer is much larger . but they both do the same job .they either step up or step down current.

Today's electronics systems require lower voltages, higher currents, higher power density, and higher efficiency than their predecessors needed. These demands necessitate the use of paralleled power MOSFETs or large-die MOSFETs. Having to use these high capacitance devices has given some designers an uneasy feeling about which approach to use.\n\nThe successful design of robust gate-drive circuitry for high voltage, very high current MOSFETs is no different than the driver circuitry designed for smaller devices. It depends on an understanding of the drive requirements, a good model to predict the results, careful attention to the physical layout of the driver board, and the selection of the proper circuit topology.\n\nFigure 1 represents a generic gate driver circuit where the switching speed is controlled by the total gate impedance (RG), the total source inductance (LS), the load resistance, and the device's characteristics. Once the load is defined and the power-switching device is selected, the fast switching speed is achieved by minimizing the two remaining parameters, RG and LS.\n\nhttp://www.techonline.com/community/ed_resource/feature_article/5652

If you have an OHM meter just ohm them. If, they Diodes you will see a reading in one direction, then change the leads around and you not get a reading. They sound like diodes to me. Resistors will have more than 2 colored strips. If I remember correct it 4.

power=voltage^2/resistance\nhigher power means lower resistance.

Voltage is dependent on the metals you use. The lemon however will have a lower output resistance. Because of this with the same load you may see more voltage the the lemon. But no load voltage will be the same.

As much as i know, all IC's have certain numbers. There are many many IC's that are performing many many different jobs. so in order to recongize which IC is doing what job it has a different number than a IC doing a different job. For example a IC used in a radio can not do the job of a IC used in TV and similarly a IC used in TV cannot do the job for a IC in radio. hence they have different numbers . so if a IC is damagerd it can only be replced by another IC of the same number.\nfor example  \n 74LS xxx  is transistor transistor logic. so if you take a microscope and look into this kind of IC you will find a lot of transistors. \nand  74HCxxx  OR Cd40xxx  series of IC are MOSFET based and if you take a microscope and look deep into these series u will find alot of MOSFET's .\nthankyou/

A CMOS inverter consists of one N-channel transistor connected to ground, and one P channel transistor connected to Vdd. Their gate pins are tied together and used as the input, and their third pins are tied together and used as the output (See the picture below for details). These transistors act like switches, controlled by the input.\n\nWhen the input is high (Vdd), it turns on the N-channel transistor and turns off the P-channel transistor. This causes the voltage at the output to be low, because the N-channel transistor is switched on, connecting the output to the ground.\n\nWhen the input is low, just the opposite happens.

The main difference is how they are turned on. An nmos requires positive Vgs to turn on, a pmos requires negative Vgs to turn on.\n\nOne possible connection for a nmos device is to ground the source (s) and then apply a voltage to the gate (g). When Vgs exceeds the on voltage (usually 2-3V or so), the device conducts between the drain (d) and s.\n\nFor a pmos device, the s is typically tied high (say, to 5V). When the gate is also at 5V, the device is off. When a lower voltage is applied, such that Vgs< -2V or so, then the device conducts between the d and s.\n\nThese are also often used in what is called an open-drain configuration. When the device is OFF, the drain is weakly pulled hi (when used with an NMOS) or low (with a PMOS) by an external resistor. Then, when the device is turned on, the drain is driven low by an NMOS or high by a PMOS. This circuit is often used to drive digital signals.\n\nI hope this helps. Most of the other answers above are good answers, but they are more geared towards the semiconductor physics. It's certainly good to know about this, but probably won't help you much with circuit analysis.
