ECE :: Network Analysis and Synthesis
-
A capacitor does not allow sudden changes
-
Assertion (A): Thevenin's theorem helps us to find current in a branch of a network for different values of impedances of that branch.
Reason (R): Thevenin's equivalent circuit replaces a network by a voltage source in series with impedance.
-
If a 'live' conductor of a public supply touches earth metal
-
If a fuse is higher than required current rating is employed in a circuit, it will
-
A series circuit has fixed resistance and variable reactance. The impedance locus will be a straight line parallel to Y-axis.
-
If the energy is supplied from a source, whose resistance is 1 ohm, to a load of 100 ohms the source will be
-
Consider the following statements :
- Tellegen's theorem is applicable to any lumped networks.
- The reciprocity theorem is applicable to linear bilateral networks.
- Thevenin's theorem is applicable to two- terminal linear active networks.
- Norton's theorem is applicable to two-terminal linear active networks.
-
An RLC series circuit is excited by a step voltage E. The units of roots of characteristic equation are
-
An excitation is applied to a system at t = T, and its response is zero for -∞ < t < T, such a system is
