Power Supply: Definition, Functions & Components

Definition: A power supply is an electronic circuit designed to provide various ac and dc voltages for equipment operation. Proper operation of electronic equipment requires a number of source voltages. Low dc voltages are needed to operate ICs and transistors. High voltages are needed to operate CRTs and other devices. …

What is a Semiconductor | Basics & Characteristics

what-is-a-semiconductor

Semiconductor Definition: Semiconductors are elements which have a conductivity between conductors and insulators. Semiconductors can be pure materials, such as silicon or germanium, or a combination of different materials such as gallium arsenide or cadmium selenide. In a doping technique, impurities are added to pure semiconductors making changes in the …

RLC Resonance, Acceptor, Tank & Rejector Circuit

RLC Resonance, Acceptor, Tank & Rejector Circuit | Q of Tuned Circuits

RLC networks are ac circuits that have resistors, capacitors, and inductors placed in the circuit to pass, reject, or control current. A circuit containing all three factors—resistance, inductance, and capacitance—is called an RLC circuit. The resulting impedance in an RLC circuit is equal to the vector addition of R in …

RC Circuit: Transient Response & Time Constant

RC Circuit: Transient Response

Definition: The response of current and voltage in a circuit immediately after a change in applied voltage is called the transient response. Refer to Figure 1. A capacitor and a resistor are connected in series across a voltage source. A circuit that contains resistance and capacitance is called an RC …

Secondary Cell: Definition & Types

Secondary Cell: Definition & Types

Definition: A secondary cell can be recharged or restored. The chemical reaction that occurs on discharge may be reversed by forcing a current through the battery in the opposite direction. This charging current must be supplied from another source, which can be a generator or a power supply.  Figure 1 …

Primary Cell: Definition & Types

primary cell types

Definition: A primary cell is a cell in which the chemical action cannot be reversed. A primary cell cannot be recharged. One might think that the chemical action of the zinc-carbon primary cell would continue to produce a voltage as long as the active ingredients of the cell were present. …
