Single Phase Transformer

A single-phase transformer is a type of power transformer. It is an electrical device that accepts converts the single phase alternating power into single phase alternating power. In this power conversion the voltage is stepped up or down. If the voltage is stepped up, the current will be stepped down and if the voltage is stepped down, the current will be stepped up.

How does the coupling factor affect the primary and secondary voltages? For example if the turns ratio in my transformer is 1:2 and the Vin is 10V, the voltage on the primary side is 10V and the voltage on the secondary side is 20V when the coupling factor (k) is 1. What will the primary and secondary voltages be if the coupling factor becomes 0.5?
