Linearly Independent

A parallel-plate capacitor is filled with a delectric meterial having resistivity (rho) and dielectric constant K.The capcitor is charged and disconnected from the charging source. The capacitor is slowly discharged through the dielectric.Show that the time constant of the discharge is independent of all gepmetrical parameters like the plate area or separation between the plates. Find this time constant.

Independent Events

Statement I : In the circuit in Fig. 7.46 , both cells are ideal and of fixed emf, the resistor R_(1) has fixed resistance and the resistance of resistor R_(2) can be varied ( but R_(2) is always non zero). Then the electric power delivered to the resistor of resistance R_(1) is independent of the value of resistance R_(2) . Statement II: If potential difference across a fixed resistance is unchanged , the poweer delivered to the resistor remains constant.
