In the given network capacitance $${C_2} = 10\mu F,\,\,{C_1} = 5\mu F$$ and $${C_3} = 4\mu F.$$ The resultant capacitance between $$P$$ and $$Q$$ will be:

Calculate the effective capacitance across XY.

In a series combination of two capacitances $$C'$$ and $$C(C> C)$$ (as shown in the circuit)

A parallel plate capacitor with air as dielectric is charged to a potential 'V' using a battery. Removing the battery, the charged capacitor is then connected across an identical uncharged parallel plate capacitor filled with wax of dielectric constant 'K' the common potential of both the capacitor is 

Find the equivalent capacitance across A and B for the arrangement shown in the figure. All capacitors are of capacitance C.

The equivalent capacitance between $$A$$ and $$B$$ in the circuit shown is:

The electric field due to the electric potential V = $$(2x^{2}-4x)$$ is 

In the adjoining figure, four capacitors are shown with the respective capacities and the $$PD$$ applied. The charge and the $$PD$$ across the $$4\ \mu\ F$$ capacitor will be:

Figure shows two capacitors connected in series and connected by a battery. The graph (B) shows the variation of potential as one moves from left and to right on the branch containing the capacitor. Then

Electrons are caused to fall through a potential difference of 1500 volt. If they were initially at rest, their final speed is
