Which of the following statements describes the difference between the primary windings and the secondary windings of an ideal 2:1 stepdown voltage transformer?
β’ Ideal transformer relationships between voltage, turns, and current β’ What a 2:1 step-down transformer means in terms of turns ratio β’ How wire turns compare between primary and secondary in a step-down transformer
β’ For a 2:1 step-down transformer, ask: is the primary voltage higher or lower than the secondary voltage, and how does that relate to the number of turns? β’ Think about which quantity is directly proportional to the number of turns: voltage, current, or resistance? β’ Consider what βidealβ means: which real-world effects (like wire size and resistance) are ignored in the definition?
β’ Identify which property of a transformer winding is directly proportional to the number of turns β’ Recall that in an ideal transformer, wire size and resistance are not the defining characteristics of the turns ratio β’ Make sure the statement you choose matches a 2:1 step-down: secondary voltage is half the primary voltage, so relate that to the turns in each winding
