A capacitor is considered to be completely charged in __________ time constant.
-
Consider the following statements associated with two port networks.
- Z12 = Z21
- Y12 = Y21
- h12 = h21
- AD - BC = 1
-
Assertion (A): The number of basic loops is equal to number of links.
Reason (R): The graph theory helps in choosing independent variables in circuit analysis.

In an R-L-C circuit, v(t) = 20 sin (314 t + 5 p/6) and i(t) = 10 sin (314 t + 2p/3). The p.f of the circuit is
-
In any network of linear impedances the current flowing at any point equal to algebric sum of currents caused to flow at that point by each of the emf taken separately with all other emfs reduced to zero. The statement represents.

The Kirchoff's laws fail in which of the following circuits?
-
A black box has one of the elements our of R, L, C. when a 220 V a supply is connected the current supplied by source is I. when a 0.1 F capacitor is connected in parallel with the box, the current is 2I. The element is

In figure, the switch has been in closed position for a long time. At t = 0, the switch is opened. At t = 0+, the current R1 is
