Equivalent Series Resistance
Normally capacitors and
indicators are used in electrical circuits which are not an ideal component however
these components are installed in the circuits with a series resistance for
better relation. The equivalent series resistances are only used in ac circuits
for standard frequencies. The following are the main components which are used
as equivalent series resistor:
Inductors
Inductors have resistance due
to its metal properties. Inductors have minimum amount of resistance in electrical
circuits and are used properly in dc power supplies for resistance. These are
also used for series resistances.
Capacitors
The capacitors have
resistances due to its lead and electrodes which causes as a series resistor. Aluminum
and electrolytic capacitors have very high amount of series resistance’s
capacitors are used for power factor improvement and for equivalent series
resistance.
