Answer :

Given

Area, A=25 cm^{2} =25×10^{-4} m^{2}

Voltage, V=6V

The separation between the plates is d= 1mm=1×10^{-3}

Formula used:

When a capacitor is connected to a capacitor, the charge can be calculated

Where

Q is the charge of the capacitor

C is the capacitance of the capacitor

V is the Voltage or potential difference across the plates of the capacitor.

Capacitance C can be calculated by the formula

Where

C is the capacitance of the capacitor

D is the separation between the capacitor plates

A is the area of a circular plate capacitor

ε₀ is the permittivity of the free space,

When the capacitor is connected to a 6V battery, Charge flow through the battery is the same as the charge that can be withstand with the capacitor.

Substitute the value of C in 1)

Work is done by the battery

Where

W is the work done by the battery

Q is the charge on the plates of the capacitor

V is the voltage across the plates of the capacitor

Charge flows through the battery is and work done by the battery is =8×10^{-10} J
