JEE MAIN - Physics (2021 - 22th July Evening Shift - No. 12)
Match List - I with List - II
Choose the correct answer from the options given below
| List - I | List - II | ||
|---|---|---|---|
| (a) | $$\omega L > {1 \over {\omega C}}$$ | (i) | Current is in phase with emf |
| (b) | $$\omega L = {1 \over {\omega C}}$$ | (ii) | Current lags behind the applied emf |
| (c) | $$\omega L < {1 \over {\omega C}}$$ | (iii) | Maximum current occurs |
| (d) | Resonant frequency | (iv) | Current leads the emf |
Choose the correct answer from the options given below
a(ii), b(i), c(iv), d(iii)
a(ii), b(i), c(iii), d(iv)
a(iii), b(i), c(iv), d(ii)
a(iv), b(iii), c(ii), d(i)
Explanation
$$\omega L = {1 \over {\omega C}},{X_L} = {X_C}$$
So current in phase with EMF
At resonance, current have maximum value.
So current in phase with EMF
At resonance, current have maximum value.
