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

1. An ideal transformer with a 450 turn
primary connected to a 600 V, 60 Hz supply
line needs to output 240 V from the
secondary. A 100 load is connected
across the secondary. How many turns the
secondary must have to output the desired
voltage? What is the current through the
load? What is the current drawn through
the primary?
