What you’d like is a device that can source or sink a given amount of current regardless of the supply voltage. Remember, in a single loop circuit, current is the same everywhere so often it ...

The 4-20 mA transmitters used in industrial current-control loops can be implemented as powered current sources, remote non-powered current sinks, or with several other I/O combinations. A useful ...

A two-wire temperature transmitter using an RTD sensor that can be used in industrial settings to connect to the control room ...

We can see how circuits work, and represent them with some simple diagrams, using basic electrical ... We can also add in some components that measure the current and the potential difference.

Current is a measure of how much electric ... so you may hear or see ‘voltage’ instead of ‘potential difference’. A circuit diagram showing a voltmeter in parallel with a lamp When two ...
