Assertion (A): In state space analysis, capacitors are taken to be in tree.

Reason (R): State variable analysis is very suitable for computer solution.

Assertion (A): Transient periods are of short duration but can result in dangerously high voltages and currents.

Reason (R): Circuit equations in transient analysis are integral differential equations.

1. The intersection of root locus branches with the imaginary axis can be determined by the use of Routh criterion
2. Segments of real axis having an odd number of real axis open loop poles plus zeros to their right are not parts of root locus
3. The number of root locus branches terminating on infinity is always zero
