definition


A rectifier is an electronic device that converts an alternating current into a direct current by using one or more P-N junction diodes. A diode behaves as a one-way valve that allows current to flow in a single direction. This process is known as rectification.



Lenz's law states that the direction of the electric current induced in a conductor by a changing magnetic field is such that the magnetic field created by the induced current opposes changes in the initial magnetic field. It is named after physicist Emil Lenz, who formulated it in 1834.



[ aw-toh-trans- fawr-mer ] SHOW IPA noun Electricity. a transformer having a single coil that serves as both a primary coil and a secondary coil. Origin of autotransformer First recorded in 1890–95; auto- 1 + transformer Words nearby autotransformer



Resistor: Device used to reduce current flow. Resistance (R R R R) Measure of how much an object resists current flow. Depends on material, length, and cross sectional area. SI units of Ohms (Ω \Omega Ω \Omega). Resistivity (ρ \rho ρ rho) Measure of how much a specific material resists current flow.



A step-up transformer is a device to transfer electrical energy from one coil to another coil with an increased voltage level. Overview of Step Up Transformer Figure 1 – A Typical Step-up Transformer A step-up transformer is used to increase the alternating voltage.



battery voltage reaching the charge voltage, then constant voltage charging, allowing the charge current to taper until it is very small. • Float Voltage – The voltage at which the battery is maintained after being charge to 100 percent SOC to maintain that capacity by compensating for self-discharge of the battery.



1. : an electronic device that consists of a small block of a semiconductor (as germanium) with at least three electrodes and is used to control the flow of electricity in electronic equipment (as a radio or computer) 2. : a radio having transistors. called also transistor radio.



transformer, device that transfers electric energy from one alternating-current circuit to one or more other circuits, either increasing (stepping up) or reducing (stepping down) the voltage.



3. Utility Programs What are the Applications of Software? Communication of Software Embedded Software Software Engineering Software Definition The software encompasses everything intangible on the computer, which cannot remain touched, such as programs and operating systems.



Software is a generic term used to describe computer programs that run on PCs, mobile phones, tablets, or other smart devices. Software is often used to describe all the functional aspects of a computer that do not refer to its physical components (hardware).



An Operating System is a software that acts as an intermediate between the hardware and the user. It is a kind of resource manager that manages both hardware and software resources of a system. There can be various resources present in the system and to manage it manually is a very very difficult task.
