Though current feedback operational amplifiers (CFOAs) are still less common in educational circles and technical literature than voltage feedback operational amplifiers (VFOAs or VFAs), they have ...

The basic components of electricity are relatively easy and logical to understand. Most electrical terms relate and get along with each other like a harmonious family. Before you tackle any electrical ...

The circuit was developed to produce a continuity tester with a low resistance mainly for checking the connections between soldered joints. Operational Amplifier (Op-Amp) – a DC coupled high gain ...

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, ...

Measuring a voltage is pretty easy: just place your multimeter’s probes across the relevant pins and read the value. Probing currents is a bit trickier, since you need to open up the circuit and place ...

Troubleshooting refrigeration equipment often requires measuring various electrical properties such as voltages, current flows, and resistances. Understanding these basic electrical fundamentals and ...

Listen to the full series on BBC Sounds. Charge is a property of a body which experiences a force in an electric field. Charge is measured in coulombs (C). Since electrons are so small and one ...

Helping meet the growing demand for current sensors by automotive companies as they migrate to 42V electrical systems, the AD8205 difference amplifier boasts of a wide, -2V to +65V input common-mode ...
