(Solved) In an induction motor, the phase reactance is ______ in comparison to phase resistance.

A) quite high
B) very small
C) slightly high
D) almost same

---

✅ Answer:

➡️ A) quite high

---

🧠 Detailed Solution

◆ Step 1: Key Concept

➡️ Induction motor is an AC machine
➡️ It operates based on electromagnetic induction

---

◆ Step 2: Nature of Windings

→ Windings are highly inductive
→ Hence inductive reactance $X$ is significant

---

◆ Step 3: Resistance Design

→ Windings are made of copper
→ Resistance kept very low to reduce losses

---

◆ Step 4: Comparison

➡️ Reactance $X$ ≫ Resistance $R$

→ So phase reactance is much higher than resistance

---

❌ Why Other Options Are Incorrect

◆ B) very small → Opposite of actual behavior
◆ C) slightly high → Underestimates difference
◆ D) almost same → Not correct

---

🔑 Key Points to Remember

◆ Induction motor is highly inductive
◆ $X\gg R$
◆ Low resistance → reduces copper loss
◆ High reactance → required for magnetic field

🎯 Final Conclusion

➡️ Phase reactance is:
Quite high compared to resistance ✔️
