A parallel plate capacitor in the figure...

A parallel plate capacitor in the figure made of circular plates each of radius R=6.0 cm has a capacitance C=100 pF. The capacitor is connected to a 230 V ac supply with a (angular) frequency of 300 rad `s^(-1)` .

What is the rms value of the conduction current ?

Text Solution

Verified by Experts

`I_("rms")=(E_("rms"))/(X_(c))=(E_("rms"))/((1)/(omegaC))=E_("rms")xx omega C`
`therefore I_("rms")=230xx300xx100xx10^(-12)=6.9xx10^(-6)A=6.9 muA`

A parallel plate capacitor with circular plates of radius 1 m has a capacitance of 1 nF. At t = 0, it is connected for charging in series with a resistor R = 1 M Omega across a 2V battery (Fig. 8.3). Calculate the magnetic field at a point P, halfway between the centre and the periphery of the plates, after t = 10^(-3) s . (The charge on the capacitor at time t is q (t) = CV [1 – exp (–t// tau) ], where the time constant tau is equal to CR.)
