MCQ
A constant voltage at different frequencies is applied across a capacitance $C$ as shown in the figure. Which of the following graphs Correctly depicts the variation of current with frequency ?
- A
- ✓
- C
- D
✓
Answer
Correct option: B.
b
(b) For capacitive circuits ${X_C} = \frac{1}{{\omega C}}$
(b) For capacitive circuits ${X_C} = \frac{1}{{\omega C}}$
$\therefore i = \frac{V}{{{X_C}}} = V\omega C$ $ \Rightarrow i \propto \omega $

→The persistence of sound in a room after the source of sound is turned off is called reverberation. The measure of reverberation time is the time required for sound intensity to decrease by $60 \,dB$. It is given that the intensity of sound falls off as $I_0 \exp \left(-c_1 \alpha\right)$ where $I_0$ is the initial intensity, $c_1$ is a dimensionless constant with value $1 / 4$. Here, $\alpha$ is a positive constant which depends on the speed of sound, volume of the room, reverberation time, and the effective absorbing area $A_e$. The value of $A_e$ is the product of absorbing coefficient (with value between $0$ and $1,1$ being a perfect absorber) and the area of the room. For a concert hall of volume $600 \,m ^3$, the value of $A_e$ (in $m ^2$ ) required to give a reverberation time of $1 s$ is closest to (speed of sound in air $=340 \,m / s$ )
