voltage drop across a resistance
41Differential 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… …
42Test probe — Typical passive oscilloscope probe being used for testing an integrated circuit. A test probe (test lead, test prod, or scope probe) is a physical device used to connect electronic test equipment to the device under test (DUT). They range from… …
43Relay — This article is about the electrical component. For other uses, see Relay (disambiguation). Automotive style miniature relay, dust cover is taken off A relay is an electrically operated switch. Many relays use an electromagnet to operate a… …
44Power MOSFET — A Power MOSFET is a specific type of Metal Oxide Semiconductor Field Effect Transistor (MOSFET) designed to handle large power. Compared to the other power semiconductor devices (IGBT, Thyristor...), its main advantages are high commutation speed …
45Emitter-coupled logic — Motorola ECL 10,000 basic gate circuit diagram[1] In electronics, emitter coupled logic (ECL), is a logic family that achieves high speed by using an overdriven BJT differential amplifier with single ended input, whose emitter current is limited… …
46Active load — An active or dynamic load is a component or a circuit behaving as a current stable nonlinear resistor. This term may refer to a component of circuit design, or to a type of test equipment. Contents 1 Circuit design 1.1 Common base example 1.2… …
47SEPIC converter — A SEPIC (single ended primary inductor converter) is a DC DC converter which allows the output voltage to be greater than, less than, or equal to the input voltage. The output voltage of the SEPIC is controlled by the duty cycle of the control… …
48Thermistor — A thermistor is a type of resistor with resistance varying according to its temperature. The word is a portmanteau of thermal and resistor . Samuel Ruben invented the thermistor in 1930, and was awarded… …
49Ground loop (electricity) — In an electrical system, a ground loop usually refers to a current, generally unwanted, in a conductor connecting two points that are supposed to be at the same potential, often ground, but are actually at different potentials. Ground loops… …
50LED circuit — In electronics, the basic LED circuit is an electrical circuit used to power a light emitting diode (LED). It consists of up to four components connected in series: a voltage source, a current limiting resistor, an LED, and optionally a switch to …
