Concept explainers

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.

Question

former is to have an approximate e.m.f. per
turn of 22 V and operate with a maximum
flux of 1.25 T. Calculate (a) the number of
primary and secondary turns, and (b) the cross-
sectional area of the core
