voltage drop across a resistance
51Decoupling capacitor — A decoupling capacitor is a capacitor used to decouple one part of an electrical network (circuit) from another. Noise caused by other circuit elements is shunted through the capacitor, reducing the effect they have on the rest of the circuit.… …
52Ohmmeter — An ohmmeter An ohmmeter is an electrical instrument that measures electrical resistance, the opposition to an electric current. Micro ohmmeters (microhmmeter or microohmmeter) make low resistance measurements. Megohmmeters (aka megaohmmeter or in …
53Schottky diode — The Schottky diode (named after German physicist Walter H. Schottky; also known as hot carrier diode) is a semiconductor diode with a low forward voltage drop and a very fast switching action.In the early days of wireless, cat s whisker detectors …

55Electrical load — If an electric circuit has a well defined output terminal, the circuit connected to this terminal (or its input impedance) is the load. (The term load may also refer to the power consumed by a circuit; that topic is not discussed here.)Load… …
56Fuel cell — For other uses, see Fuel cell (disambiguation). Demonstration model of a direct methanol fuel cell. The actual fuel cell stack is the layered cube shape in the center of the image A fuel cell is a device that converts the chemical energy from a… …
57Plasma channel — A plasma channel is a conductive channel of plasma. A plasma channel can be formed in these ways: *With a high powered laser that operates at a certain frequency that will provide enough energy for an atmospheric gas to break into its ions, or… …
58Ammeter — Amperemeter redirects here. For the unit of measurement, see Ampere meter. Demonstration model of a moving iron ammeter. As the current through the coil increases, the plunger is drawn further into the coil and the pointer deflects to the right …
59Short circuit — A short circuit (sometimes abbreviated to short or s/c) allows a current along a different path from the one intended. The electrical opposite of a short circuit is an open circuit , which is an infinite resistance between two nodes. It is common …
60AC/DC (electricity) — Electronic equipment designed to run off either alternating current (ac) or direct current (dc) power is described as ac/dc or AC/DC equipment. This usage has become obsolete with the vacuum tube. Some equipment is inherently able to use either… …
