The capacitor offers zero resistance to

The collector - base junction of a transistor offers ……….resistance to current .

A capacitor is connected across an inductor. At time t = 0 charge on the capacitor is equal to 1/sqrt2q_"max" , where q_"max" is the maximum charge on the capacitor. The time t, at which the energy stored in the capacitor is equal to the energy stored in the inductor is (The inductance of the inductor is L and capacitance of the capacitor is C. Resistance of the circuit is zero)

Assertion: At 0K germanium is a superconductor. Reason: At 0K germanium offers zero resistance.

Assertion : The switch S shown in the figure is closed at t = 0 . Initial current flowing through battery is (E)/(R + r) Reason : Initially capacitor was uncharged, so resistance offered by capacitor at t = 0 is zero

Assertion : The switch S shown in the figure is closed at t = 0 . Initial current flowing through battery is (E)/(R + r) Reason : Initially capacitor was uncharged, so resistance offered by capacitor at t = 0 is zero

An alternating voltage V=V_(0) sin omegat is connected to a capacitor of capacity C_(0) through an AC ammeter of zero resistance. The reading of ammeter is
