voltage drop across a resistance
61Watt's law — is an improper name used for the Basic Power Formula: :P = V cdot I where :P is the power in watts:V is the potential difference in volts:I is the current in amperesThe basic power formula is used to calculate the electrical power P dissipated in …
62Power (physics) — In physics, power is the rate at which energy is transferred, used, or transformed. For example, the rate at which a light bulb transforms electrical energy into heat and light is measured in watts the more wattage, the more power, or what is the …
63Ideal switch — In electronics engineering, ideal switch is the term to describe the condition for a switch that: * has no current limit during its ON state * has infinity resistance during its OFF state * has no voltage drop across the switch during its ON… …
64Practical switch — In electronics engineering, practical switch is the term to describe the condition for a switch that:* has finite resistance during its OFF state * has limited blocking voltage during its OFF state * has limited conduction current during its ON… …
65Electronic amplifier — A practical amplifier circuit An electronic amplifier is a device for increasing the power of a signal. It does this by taking energy from a power supply and controlling the output to match the input signal shape but with a larger amplitude. In… …
66Shunt (electrical) — In electronics, a shunt is a device which allows electric current to pass around another point in the circuit. The term is also widely used in photovoltaics to describe an unwanted short circuit between the front and back surface contacts of a… …
67Miller theorem — refers to the process of creating equivalent circuits. It asserts that a floating impedance element supplied by two voltage sources connected in series may be split into two grounded elements with corresponding impedances. There is also a dual… …
68Operational 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… …
