Which of the following describes the relationship for an ideal step-up transformer?
AVs > Vp and Is > Ip
BVs > Vp and Is < Ip
CVs < Vp and Is > Ip
DVs < Vp and Is < Ip
✓ Correct Answer: B — Vs > Vp and Is < Ip
A step-up transformer increases voltage (Vs > Vp) and must decrease current (Is < Ip) to conserve power.
