The rms value of potential difference \(v\) shown in the figure is
- A \(\frac{\mathrm{v}_{0}}{2}\)
- B \(\mathrm{v}_{0}\)
- C \(\frac{v_{0}}{\sqrt{3}}\)
- D \(\frac{v_{0}}{\sqrt{2}}\)
Answer & Solution
Correct Answer
(D) \(\frac{v_{0}}{\sqrt{2}}\)
Step-by-step Solution
Detailed explanation
\(\mathrm{V}_{\mathrm{rms}}^{2} \times \mathrm{T}=\mathrm{V}_{0}^{2} \times \frac{\mathrm{T}}{2}+0\) \(\mathrm{~V}_{\mathrm{rms}}^{2}=\frac{\mathrm{V}_{0}^{2}}{2} \quad \mathrm{~V}_{\mathrm{rms}}=\frac{\mathrm{V}_{0}}{\sqrt{2}}\)

When a DC voltage is applied at the two ends of a circuit kept in closed box, it is observed that the current gradually increases from zero to a certain value and then remains constant. What do you think that the circuit contains?WBJEE 2020 Easy - A glass slab consists of thin uniform layers of progressively decreasing refractive indices RI (see figure) such that the RI of any layer is \(\mu-m \Delta \mu\). Here, \(\mu\) and \(\Delta \mu\) denote the \(\mathrm{RI}\) of 0 th layer and the difference in RI between any two consecutive layers, respectively. The integer \(m=0,1,2,3, \ldots\) denotes the numbers of the successive layers. A ray of light from the oth layer enters the 1st layer at an angle of incidence of \(30^{\circ}\). After undergoing the mth refraction, the ray emerges parallel to the interface. If \(\mu=1.5\) and \(\Delta \mu=0.015,\) the value of \(m\) is
