High-precision laboratory measurements of electrical quantities are used in experiments to determine fundamental physical properties such as the charge of the electron or the speed of light, and in the definition of the units for electrical measurements, with precision in some cases on the order of a few parts per million. Less precise ...
Electricity meter: Measures the amount of energy dissipated ESR meter: Measures the equivalent series resistance of capacitors Frequency counter: Measures the frequency of the current Leakage tester: Measures leakage across the plates of a capacitor LCR meter: Measures the inductance, capacitance and resistance of a component Megger tester
High Definition Television, any television system with more than 625 scan lines. headphone An audio transducer or pair of transducers arranged to be worn on (or in) the ear. heat transfer The study of the flow of heat energy; heat transfer concerns dictate major design features of most electrical and electronic systems. heatsink
Instrumentation engineering is the science of the measurement and control of process variables within a production or manufacturing area. [1] Meanwhile, control engineering , also called control systems engineering, is the engineering discipline that applies control theory to design systems with desired behaviors.
A normal experiment may involve 1–10 mL solution with an analyte concentration between 1 and 10 mmol/L. More advanced voltammetric techniques can work with microliter volumes and down to nanomolar concentrations. Chemically modified electrodes are employed for the analysis of organic and inorganic samples.
In electrical engineering and electronics, a network is a collection of interconnected components. Network analysis is the process of finding the voltages across, and the currents through, all network components. There are many techniques for calculating these values; however, for the most part, the techniques assume linear components.
The gold-leaf electroscope was one of the instruments used to indicate electric charge. [1] It is still used for science demonstrations but has been superseded in most applications by electronic measuring instruments. The instrument consists of two thin leaves of gold foil suspended from an electrode.
