Exempel på hur man kan använda VOLTAGE i en mening

• For example, in an analog audio signal, the instantaneous signal voltage varies continuously with the pressure of the sound waves.
• An ammeter usually has low resistance so that it does not cause a significant voltage drop in the circuit being measured.
• If an evacuated glass tube is equipped with two electrodes and a voltage is applied, glass behind the positive electrode is observed to glow, due to electrons emitted from the cathode (the electrode connected to the negative terminal of the voltage supply).
• Either an electric current is passed through the wire of the coil to generate a magnetic field, or conversely, an external time-varying magnetic field through the interior of the coil generates an EMF (voltage) in the conductor.
• In power engineering, a "bus" is any graph node of the single-line diagram at which voltage, current, power flow, or other quantities are to be evaluated.
• An amplifier, electronic amplifier or (informally) amp is an electronic device that can increase the magnitude of a signal (a time-varying voltage or current).
• F-waves are the second of two late voltage changes observed after stimulation is applied to the skin surface above the distal region of a nerve, in addition to the H-reflex (Hoffman's Reflex) which is a muscle reaction in response to electrical stimulation of innervating sensory fibers.
• When the current flowing through the coil changes, the time-varying magnetic field induces an electromotive force (emf) (voltage) in the conductor, described by Faraday's law of induction.
• The study of ion channels often involves biophysics, electrophysiology, and pharmacology, while using techniques including voltage clamp, patch clamp, immunohistochemistry, X-ray crystallography, fluoroscopy, and RT-PCR.
• A simple magneto (an electrical generator using permanent magnets) is able to produce relatively low voltage electricity, however it is unable to produce the high voltages required by a spark plug as used in most modern engines (aside from diesel engines).
• An operational amplifier (often op amp or opamp) is a DC-coupled electronic voltage amplifier with a differential input, a (usually) single-ended output, and an extremely high gain.
• A voltage or current applied to one pair of the transistor's terminals controls the current through another pair of terminals.
• A thermocouple produces a temperature-dependent voltage as a result of the Seebeck effect, and this voltage can be interpreted to measure temperature.
• The volt (symbol: V) is the unit of electric potential, electric potential difference (voltage), and electromotive force in the International System of Units (SI).
• Analog voltmeters move a pointer across a scale in proportion to the voltage measured and can be built from a galvanometer and series resistor.
• The primary benefit of the circuit is its ability to provide extremely accurate measurements (in contrast with something like a simple voltage divider).
• In electrochemistry, electrode potential is the voltage of a galvanic cell built from a standard reference electrode and another electrode to be characterized.
• Alternating current is normally preferred as its voltage may be easily stepped up by a transformer in order to minimize resistive loss in the conductors used to transmit power over great distances; another set of transformers is required to step it back down to safer or more usable voltage levels at destination.
• Vibrator (electronic), an electronic component in DC power supplies for generating high voltage made obsolete by the late 1960s.
• This ability to change conductivity with the amount of applied voltage can be used for amplifying or switching electronic signals.
