Advantages & disadvantages of Laser diodes
The advantage of Laser diodes are given below: The Laser diode operates in lower power as compared to other laser. It gives high power output as compared to other lasers. Laser diode is smaller in size as
Difference between JFET and MOSFET
Following are the JFET (junction field effect transistor) and MOSFET (metal oxide semiconductor field effect transistor) . JFET MOSFET The JFET stand for junction field effect transistor. MOSFET stand for metal oxide semiconductor field effect transistor. JFET
Advantage, Disadvantage and application of Schottky diode
The advantage of Schottky diode some of below It has a very low cut-in voltage of about 0.3 V. Schottky diode has very low switching time. Schottky diode has very low power consumption. it has a very
Photodiode
What is a Photodiode? The photodiode is a two terminal PN junction device which is operated in reverse bias. It has a small transparent window which allows light to strike the PN junction. The photodiode is a
Metal oxide semiconductor field effect transistor (MOSFET)
The MOSFET stands for Metal Oxide Semiconductor Field Effect Transistor. It has a three terminal source, gate and drain terminals just like JFET. The gate terminal in MOSFET is insulated from the channel therefore sometimes MOSFET is
Light Depending Resistor (LDR)
Light dependent resistor (LDR) is a kind of variable non-linear resistor whose value of resistance depends on the value of light incident on it. LDR is also called as photo resistor, photo conductors, photo conductive cells or
Colour band table of resistor
Following table is commonly used for all colour band of resistor Sr. No Colour 1st Band 2nd Band 3rd Band Tolerance 1 Black 0 0 100 – 2 Brown 1 1 101 – 3 Red 2 2
Colour code table of capacitor
Following are the colour code table of an capacitor Sr. No Colour Digit Multiplier Tolerance Voltage 1 Black 0 1 ± 20% – 2 Brown 1 10 100 3 Red 2 100 200 4 Orange 3 1000
Semiconductors
What is a semiconductor? The semiconductors are the type of material which electrical property lies between conductor and insulator. Semiconductors act like insulator at very low temperature, as the temperature increases conduction of semiconductor increases. Semiconductors in
Unijunction Transistor (UJT)
Electronic devices are mainly used in switching. BJT acts as a switch and is very simplest method but it has low efficiency and many faults. Therefore UJT and SCR are more useful in electronic circuit for switching
