The electric charges are distributed in a small volume. The flux of the electric field through a spherica surface of radius 10 cm surrounding the total charge is 20 V - m . The flux over a concentric sphere of radius 20 cm will be

What is a battery ?

Air filled capacitor is charged by a battery and after charging battery is removed. A slab of dielectric material is inserted in it to fill the space completely . The electric field in the capacitor is

The anodic half-cell of lead-acid battery is recharged using electricity of 6 Faraday. The amount of PbSo_(4) electrolyzed in moles during the process is__________.

Statement I: Internal resistance of a battery is drawn parallel to a battery in electical circuit. Statement II: Heat generated in a battery is due to internal resistance.

A parallel plate capacitor is connected to a battery of emf V volts. Now a slab of dielectric constant k=2 is inserted between the plates of capacitor without disconnecting the battery. The electric field between the plates of capacitor after inserting the slab is E= (PV)/(2d) . Find the value of P.
