We’re used to those high voltage projects which use a self-oscillating transformer circuit with a TV flyback winding, and we ...

the easiest way is to use a shunt resistor and measure the voltage across it, and for AC you could use a current transformer. But the advent of the Hall-effect sensor has provided us a much better ...

before electrical power leaves a power station – it is transferred at high voltages ... work with an alternating current (ac) input. This transformer steps up the voltage by reducing the current.
