Expression for voltage sensitivity Is `theta/V=(NAB)/(CR)`Why It Is independent of number of turns ?

Expression for voltage sensitivity Is theta/V=(NAB)/(CR) How will you increase the voltage sensitivity?

When 240V was applied to the primary of a transformer, the voltage in the secondary was 12V. If the number of turns in the primary is 4,800 what will be the number of turns in the secondary2

There are 10000 turns in the primary and 500 turns in the secondary of a transformer.The primary voltage is 240 V and intensity of current in the primary is 0.1 A.Find the intensity of current if the secondary voltage is 12V ?

A transformer is used to change the alternating voltage to a high or low value. A power transmission line feeds input power of 2300 V to a stepdown transformer with its primary windings having 4000 turns. What should be the number of turns in the secondary in order to get output power at 230 V?
