Match List-I with List-II. List - I List - II (a) ω L > 1 ω C (i) Current is in phase with emf (b) ω L = 1 ω C (ii) Current lags behind the applied emf (c) ω L < 1 ω C (iii) Maximum current occurs (d) Resonant frequency (iv) Current leads the emf Choose the correct answer from the options given below.
Options
- A(a) - (ii) ; (b) - (i) ; (c) - (iv) ; (d) - (iii)
- B(a) - (ii) ; (b) - (i) ; (c) - (iii) ; (d) - (iv)
- C(a) - (iii) ; (b) - (i) ; (c) - (iv); (d) - (ii)
- D(a) - (iv) ; (b) - (iii) ; (c) - (ii); (d) - (i)
Correct answer
A. (a) - (ii) ; (b) - (i) ; (c) - (iv) ; (d) - (iii)
Step-by-step solution
(a) For x L > x C , voltage leads the current (ii) (b) For x L = x C , voltage & current are in same phase (i) (c) For x L < x C , current leads the voltage (iv) (d) For resonant frequency x L = x C , current is maximum (iii)
