🔍 Key Concepts

• Autotransformer tap percentages along the winding between points X and Y • Relationship between fraction of winding used and the fraction of source voltage delivered to the load • How the load leads are actually connected to the transformer terminals in Figure B

💭 Think About

• Trace the circuit in Figure B: from the circuit breaker, through point X, through the winding to point Y, and then to the load. Which two points actually define the load voltage? • Look at where the load is connected relative to the 25%, 50%, and 75% markings. Is the load across the entire winding, or only a portion of it? • If the full X–Y winding represents 100% and is supplied with 220 VAC, what voltage would appear across just 25%, 50%, or 75% of that same winding?

✅ Before You Answer

• Identify exactly which tap(s) the load is connected across in Figure B before deciding. • Confirm that voltage is proportional to the percentage of total turns in a transformer winding: (V_{tap} = \text{(tap %)} \times V_{source}). • Compare your calculated tap voltage with the closest matching choice from the answers.
