The ratio of the number of turns of the primary coil to the secondary coil of an ideal transformer is \(5: 1\). The primary is connected to 220 V supply. What is the output power of the transformer if the output resistance is \(11 \Omega\) ?
- A 1100 W
- B 100 W
- C 176 W
- D 1760 W
Answer & Solution
Correct Answer
(C) 176 W
Step-by-step Solution
Detailed explanation
For an ideal transformer, the relation between the primary voltage \(V_p\), secondary voltage \(V_s\), and the number of turns \(N_p\) and \(N_s\) is given by \(\dfrac{V_s}{V_p} = \dfrac{N_s}{N_p}\). Given \(\dfrac{N_p}{N_s} = \dfrac{5}{1}\), we have…
