An alternating current in a primary winding induces ... but it’s way more clever than a simple AC transformer circuit. It’s both a TV timebase moving the spot horizontally across the screen ...

But for circuits where weight, volume, or cost are a major concern, a transformer may be omitted ... using a series capacitor to limit current. To bring the voltage to an acceptable level, a ...

power is measured in watts (W) potential difference is measured in volts (V) current is measured in amperes, also referred to as amps (A) A step-down transformer converts 11,500 V into 230 V.
