constant-voltage power supply
91Electrochemistry — is a branch of chemistry that studies chemical reactions which take place in a solution at the interface of an electron conductor (a metal or a semiconductor) and an ionic conductor (the electrolyte), and which involve electron transfer between… …
92Direct current — (red curve). The horizontal axis measures time; the vertical, current or voltage. Direct current (DC) is the unidirectional flow of electric charge. Direct current is produced by such sources as batteries, thermocouples, solar cells, and… …

94Linear regulator — In electronics, a linear regulator is a voltage regulator based on an active device (such as a bipolar junction transistor, field effect transistor or vacuum tube) operating in its linear region (in contrast, a switching regulator is based on a… …
95Operational amplifier applications — This article illustrates some typical applications of operational amplifiers. A simplified schematic notation is used, and the reader is reminded that many details such as device selection and power supply connections are not shown. Contents 1… …
96Battery charger — This unit charges the batteries until they reach a specific voltage and then it trickle charges the batteries until it is disconnected …
97Differential amplifier — symbol The inverting and non inverting inputs are distinguished by − and + symbols (respectively) placed in the amplifier triangle. Vs+ and Vs− are the power supply voltages; they are often omitted from the diagram for simplicity, but of course… …
98DC to DC converter — In electronic engineering, a DC to DC converter is a circuit which converts a source of direct current (DC) from one voltage level to another. It is a class of power converter. Usage DC to DC converters are important in portable electronic… …
99particle accelerator — accelerator (def. 7). [1945 50] * * * Device that accelerates a beam of fast moving, electrically charged atoms (ions) or subatomic particles. Accelerators are used to study the structure of atomic nuclei (see atom) and the nature of subatomic… …
