Series LCR at resonance: impedance is: MCQ with Answer and Explanation

Question Report Error

Series LCR at resonance: impedance is:

A. Maximum

B. Zero

C. Minimum (=R)

D. Infinite

Answer: Option C

Solution (By JKExamLibrary)

Resonance: X_L = X_C ⇒ they cancel ⇒ Z = R (minimum). Current maximum at resonance. Memory tip: 'Series resonance: Z_min = R; parallel: Z_max'. AC circuit concept frequently tested in competitive exams.

Escape velocity depends on:

A. Atmosphere

B. Planet mass and radius

C. Projectile mass

D. Launch angle

View Answer & Solution Discuss

Correct Answer: Option B

Explanation:
v_e = √(2GM/R): depends on planet's M and R, independent of projectile mass or launch direction. Memory tip: 'v_e ∝ √(M/R); property of planet, not projectile'. Gravitation concept frequently tested in competitive exams.
