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 ...

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 ...

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 ...

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 ...

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, ...

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 ...

When it comes to low-voltage and AC and DC difference in shock risk, many workers may be confused. Low-voltage is not defined by OSHA in regards to electrical safety and severity of shock. Related to ...

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 ...

The circuit was designed to create a spare and reserve power source with the use of batteries during the absence of power from the mains. BD139 – NPN power transistor used for driver stages in hi-fi ...
