The average value of potential difference $V$ shown in figure is
$V_0$
$\frac{V_0}{2}$
$\frac{V_0}{4}$
$\frac{2V_0}{3}$
What are $A.C.$ signals ?
The charge in an $LC$ circuit with negligible resistance oscillates as given by equation $\frac{{{d^2}q}}{{d{t^2}}} + 16{\pi ^2}q = 0$. If the charge is maxiumum equal to $24\,\mu C$ at $t = 0$, find the charge at $t = \frac{1}{{12}}\,s$............$\,\mu C$
The variation of $EMF$ with time for four types of generators are shown in the figures. Which amongst them can be called $AC$ ?
The $AC$ voltage across a resistance can be measured using a
Which of the following units denotes the dimension $\frac{{M{L^2}}}{{{Q^2}}}$ where $Q$ denotes the electric charge?
