What is the voltage output of a transformer whose turns ratio is 6:1 and has a primary voltage of 240VAC?

Explanation:
Voltage in a transformer scales with the turns ratio. For an ideal transformer, Vs = Vp × (Ns/Np). A turns ratio of 6:1 means Ns/Np = 1/6, so the secondary voltage is 240 VAC × 1/6 = 40 VAC. The other options would require different ratios or indicate stepping up rather than stepping down. So the voltage output is 40 VAC.
