A parallel plate capacitor consists of two circular plates each of radius 12 cm and separated by 5.0 mm. The capacitor is being charged by external source. The charging current is constant and is equal to 0.15 A. The rate of change of potential difference between the plates will be :

Answer»

`1.873 xx 10^(7) V // s`
`1.873 xx 10^(8) V // s`
`1.873 xx 10^(9) V // s`
`1.873 xx 10^(10) V // s`

Solution :`(dV)/(DT)=(I)/(C)=(I.d)/(A epsilon_(0))=1.87 xx 10^(9) V // s`
