Statement: The voltage drop across a series resistor is directly proportional to the magnitude of its resistance. Voltage Divider Circuit and Formula Consider a series circuit comprising of ‘n’ total resistors. The voltage divided across resistors Rx can be found from formula: Let’s understand it in series circuit with two resistors. VDR in Two Series … Read more

Our exploration of thyristors begins with a device called the four-layer diode, also known as a PNPN diode, or a Shockley diode after its inventor, William Shockley. This is not to be confused with a Schottky diode, that two-layer metal-semiconductor device known for its high switching speed. A crude illustration of the Shockley diode, often seen in textbooks, is a … Read more

Like its bipolar cousin, the field-effect transistor may be used as an on/off switch controlling electrical power to a load. Let’s begin our investigation of the JFET as a switch with our familiar switch/lamp circuit: Remembering that the controlled current in a JFET flows between source and drain, we substitute the source and drain connections of a … Read more
Insulated gate field-effect transistors are unipolar devices just like JFETs: that is, the controlled current does not have to cross a PN junction. There is a PN junction inside the transistor, but its only purpose is to provide that nonconducting depletion region which is used to restrict current through the channel. Here is a diagram … Read more
