🔍 Key Concepts

• Notice the single winding with taps at 25%, 50%, and 75% – think about what kind of device uses one coil with multiple voltage points instead of separate primary and secondary windings. • Compare a simple inductor/choke (used for filtering or power factor) with a transformer-type device that can change voltage levels for the load. • Look at how source current and the labeled “XFMR current” share the same winding segment – this is a clue about the device’s basic construction.

💭 Think About

• Does a fluorescent ballast, power factor inductor, or noise choke normally have multiple taps marked in percentage of winding, or is that more typical of something used to vary voltage? • If one winding is serving both the source side and the load side, what family of transformer does that suggest, compared to a standard two-winding transformer? • Which choice describes a device that can provide different output voltages (like 25%, 50%, 75%) to a load from the same winding?

✅ Before You Answer

• Verify which option is a transformer with a single tapped winding shared between input and output. • Eliminate any options that are just simple series inductors without multiple taps or transformer action. • Confirm which device is commonly used between a breaker and a load to adjust voltage level rather than only to correct power factor or filter noise.
