A transformer-based power supply is going ... Since the capacitor passes some current as long as the DC voltage doesn’t exceed the AC peaks, you can get practically any, or multiple, voltages ...

He chose a disk shaped transformer because they look cooler, fair enough.. (oh and they reduced inter-winding capacitance and the voltage difference ... 8kV at a very high current, producing ...

The higher the current in a cable, the greater the heat loss to the surroundings. This means that high currents waste more energy than low currents. When a transformer steps up voltage ...

Transformers will only work with an alternating current (ac) input. This transformer steps up the voltage by reducing the current. Step-down transformers are used to decrease or 'step down' voltages.
