The objective of connecting a resistance and capacitance
across gate circuit is to protect the SCR against
Answer Posted / gurusaran
The objective is to protect SCR against high dV/dt.The
protection is called as Snubber Circuit.It is a series
combination of resistor 'R' and capacitor 'C'.The capacitor
'C' is used to limit the dv/dt across the SCR.The resistor 'R'
is used to limit high discharging current through the SCR.

True or false question. 1.The fuse provide phase and neutral 2.power loss in electrical circuit can take place in (resistance or inductance or capacitance). 3.two phase system each phase has separated by a phase difference of (90 or 180 or 270 or 45). 4.3 phase balanced star connected load neutral current shall be (line current or phase current or zero or unity)
