Current is a measure of how much electric charge flows through a circuit. The more charge that flows, the bigger the current. Current is measured in amperes. The symbol for ampere is A. For example, ...

What Is The Hall Effect? Discovered by Edwin Hall in 1879, the Hall effect is a phenomenon when voltage (potential difference) is generated across a current-carrying conductor when it is placed in a ...

Editor’s note: This month’s guest author is John P. Griffith, a systems engineer for the Interface group at TI, where he has supported CAN and RS485 transceivers in both applications and systems ...

This article focuses on single-cell electrophysiology and introduces the fundamentals of electrophysiological investigation by describing the ionic basis of action potentials and the different ...

The induced voltage produces an induced current if the conductor is connected in a complete circuit. As with all currents, the induced current creates a magnetic field around itself. Note that this ...

Last month we examined the operation and application of the potential starting relay. This month we will cover voltage specifications of the potential relay. Compressors may have one of three voltage ...

Genetically encoded voltage sensors are coming of age, but their use still poses challenges that must be addressed from multiple angles. Neurons process information with the help of electrical signals ...

(Nanowerk News) Photothermoelectric (PTE) effect involves two energy conversion processes: photothermal conversion and thermoelectric effect. When the incident light is locally absorbed, a temperature ...

Potential relays are commonly found on many smaller, single-phase, capacitor-start, capacitor-run motors in the HVACR industry. Their function is to assist in starting the electric motor. Potential ...
