Diode Clipping Circuit
Can someone please answer the following questions about electronic components for an assignment? Please!!?
I need all the questions (below) answered for each component listed below:
1. FOR EACH COMPONENT EXPLAIN ITS PURPOSE.
2. DESCRIBE WHAT IT WOULD DO IN A CIRCUIT.
3. IS IT A SEMI CONDUCTOR.
(what is the difference in question 2 and 3)
-resistor
-variable resistor
-electrolytic capacitator
-MKT capacitor
-green cap capacitor
-NPN transistor
-PNP transistor
-LED
-power diode
-signal diode
-momentary switch
-toggle switch
-battery clip
-transformer
-speaker
-light dependant resistor
-microphone
if you dont know all of them, can you please give me some web sites, thanks.!!
Resistor - controls the flow of current - same - Not a semi
Variable Resistor - Same as Above adjustable - not a semi
Electrolytic Cap - Holds a charge, blocks DC current, Polarized for use in one polarity (+/-) only, tend to be high value - filters out noise - not a semi
MKT Capacitor - Same as Above but usually smaller in value range - not a semi
Green Cap Capacitor - very small value but like other Caps
NPN Transistor - semiconductor device, regulates current - uses positive current from Base to Emitter to increase current through the device, used in amplifier and switching circuits.
PNP Transistor - Same as NPN but uses negative current from base to collector to control current through the device.
LED Light Emitting Diode - semiconductor device that emits light when current passes through it
Power diode - semiconductor device that allows large amounts of current to flow in one direction only - used in power circuits to suppress transformer fly back and to rectify AC voltage to DC
Signal Diode - semiconductor device like power diode but with smaller current capacity - used in logic circuits and small signal applications
Momentary Switch - device that provides momentary current path - can be semiconductor or mechanical
Toggle switch - device that provides switchable stable current path - can be semiconductor or mechanical but usually thought of in machanical switch sense
Battery Clip - mechanical device that connects a circuit to a battery
Transformer - two or more coils of wire wound on a common core that magnetically transfers AC voltages from one coil to another - not a semi
Speaker - device that acts as a transducer to convert voltages to sound - can be semi or coil and magnet
Light Dependant Resistor - a resistor (see above) whose value changes when light strikes the device
Microphone - exactly like a speaker only works in reverse to change sound waves into electrical signals

please explain me about clipping and clamping circuits?
it is in diode uses
1) Clipping : clipping is nothing but the process of cutting / chopping off any desired amount of an AC signal / waveform.
for example, if u have a signal of 7 VAC, and u want to feed it to a system which accepts only 5 V signal, then clipper can be used to chop off excess 2 V. diodes can be used in Clipping.
where as,
2) Clamping is raising / adding / boosting the input signal by any desired voltage value.
Ex; consider an electrical systems accepts only 5 V as an i/p, but u have 3 V signals. By Clamping this i/p, u can raise it value to apparent 3+2=5 V value.
note: clam piing is no Amplifying.
