Question

A step-down transformer has 2500 turns on its primary and 5.0´ 101 turns on its secondary. If the potentialdifference across the primary is 4850 V, what is the potentialdifference across the secondary?

Explanation / Answer

   Vp /VS   =   NP /NS    V   =   Voltage,         N   =   No.of turns    subscript P is for priamry and S forsecondary    4850 /VS    =   2500 /50    Voltage acrosssecondary   VS   =   4850* 50 / 2500   =   97.0   V    V   =   Voltage,         N   =   No.of turns    subscript P is for priamry and S forsecondary    4850 /VS    =   2500 /50    Voltage acrosssecondary   VS   =   4850* 50 / 2500   =   97.0   V
