The turn ratio of a transformers is given as 2 : 3. If the current through the primary coil is 3 A, thus calculate the current through load resistance
Text Solution
Verified by ExpertsThe correct answer is:
C
For an ideal transformer output power = input power,
If 
and 
be the currents in the primary and secondary at any instant and the energy losses be zero, then power in
secondary = power in primary
Given, 
When voltage is stepped-up the current is correspondingly reduced in the same ratio and vice-versa.
