Three identical charged capacitors each of capacitance $5 \,\mu F$ are connected as shown in figure. Potential difference across capacitor $(3)$, long time after the switches $K_1$ and $K_2$ are is closed, is ............ $V$
If a charged spherical conductor of radius $10\,cm$ has potential $V$ at a point distant $5\,cm$ from its centre, then the potential at a point distant $15\,cm$ from the centre will be
A capacitor of capacitance $C =900\,pF$ is charged fully by $100\,V$ battery $B$ as shown in figure $(a)$. Then it is disconnected from the battery and connected to another uncharged capacitor of capacitance $C =900\,pF$ as shown in figure $(b)$. The electrostatic energy stored by the system $(b)$ is $\dots\dots\times 10^{-6}\,J$
Twenty seven drops of same size are charged at $220\, \mathrm{~V}$ each. They combine to form a bigger drop. Calculate the potential of the bigger drop. (In $\mathrm{~V}$)
The plates of a parallel plate capacitor with no dielectric are connected to a voltage source. Now a dielectric of dielectric constant $K $ is inserted to fill the whole space between the plates with voltage source remaining connected to the capacitor.
Two capacitors of $2$ $\mu F$ and $3$ $\mu F$ are charged to $150$ $volt$ and $120$ $volt$ respectively. The plates of capacitor are connected as shown in the figure. A discharged capacitor of capacity $1.5$ $\mu F$ falls to the free ends of the wire. Then
