Consider the circuit shown where C1= 6 μF

A cylindrical conductor has uniform cross-section. Resistivity of its material increase linearly from left end to right end. If a constant current is flowing through it and at a section distance x from left end, magnitude of electric field intensity is E , which of the following graphs is correct and the charged capacitor is [...]

Following figures show four situations in which positive and negative charges move horizontally through a region and give the rate at which each charge moves. Rank the situations according to the effective current through the region greatest first. and the charged capacitor is connected to the uncharged capacitor C2 by closing S2. C2 = 3 [...]

The relaxation time τ is nearly independent of applied E field whereas it changes significantly with temperature T. First fact is (in part) responsible for Ohms law whereas the second fact leads to variation of ρ with temperature. Elaborate why? and the charged capacitor is connected to the uncharged capacitor C2 by closing S2. C2 [...]

In the circuit shown in figure initially key K 1 is closed and keys K 2 is open. Then K 1 ​ is opened and K 2 is closed (order is important). [Take Q 1 ′and Q 2 ′ ​as charges on C 1 and C 2 ​ and V 1 and V 2 as [...]

Consider the circuit shown where C1= 6 μF, C2 = 3 μF and V = 20 V. Capacitor C1 is first charged by closing the switch S1. Switch S1 is then opened, and the charged capacitor is connected to the uncharged capacitor C2 by closing S2. and the charged capacitor is connected to the uncharged [...]
