An ammeter is always connected in series with the component whose current you want to measure. This means it is placed ...

For electricity to flow, everything needs to be connected in a big ring. It’s called a circuit. For example, the lights in most houses and flats are part of a circuit controlled by the consumer unit, ...

If you ever work with a circuit that controls a decent amount of current, you will often encounter a FET – a Field-Effect Transistor. Whether you want to control a couple of powerful LEDs, switch a ...

There are many cases where a power supply needs an internal current-limiter function, usually built using a current sensor, a control circuit, and a pass transistor. The current sensor itself can be a ...

Inductance is the link between electric circuits and magnetic fields. Voltage and current sine waves are in-phase when they peak and cross the zero axis at the same time. However, this rarely happens ...

One type of starting relay used on fractional horsepower compressors is the positive temperature coefficient (PTC) relay. It performs the same function as a current relay or potential relay but in a ...

ROHM Semiconductor today announced the development of the TLR1901GXZ, an ultra-compact CMOS operational amplifier (op amp) that achieves the industry’s lowest operating circuit current. Optimized for ...
