Transistor

A semiconductor device consisting of two P-N junctions formed by sandwiching, either p-type or n-type semiconductor between a pair of opposite type is known as a transistor. It is a device which transfers a week signal from low resistance circuit to high resistance circuit and is named as transistor. “Trans” means transfer property and “istor” …

P-N Junction Diode

A P-N junction diode is a combination of two semiconductor materials, one is P-type semiconductor and another is N-type semiconductor. It is also called as simply P-N junction or semiconductor diode. The diode has two terminals, P-type semiconductor is called anode and N-type semiconductor is called cathode. It allows the current in one direction and …

Multimeter and its Types

Analog Multimeter, Multimeter, Image of Multimeter

Multimeter The multimeter is widely used in every measurement techniques. With the help of multimeter we can measure various quantities such as resistance, AC & DC voltage, current, capacitance etc. A multimeter is a voltmeter, ammeter, and millimeter combined together. There, it is also known as VOM (Volt-Ohm Millimeter). Multimeter may likewise have different capacities, …

Identify the terminals of a Transistors

Transistor The transistor is a two PN diodes back to back combination where P-type or N-type semiconductor sandwich between another type of semiconductor material. Mainly there is two types of transistors, NPN and PNP, with different circuit symbols. The letters of transistors (PNP & NPN) refers to the layers of P-type or N-type semiconductor material …
