Answer:
The reflected resistance in the primary winding is 6250 Ω
Explanation:
Given;
number of turns in the primary winding,
= 50 turns
number of turns in the secondary winding,
= 10 turns
the secondary load resistance,
= 250 Ω
Determine the turns ratio;

Now, determine the reflected resistance in the primary winding;

Therefore, the reflected resistance in the primary winding is 6250 Ω
