Answer / master rapper

a closing resistor is attached to the poles of a circuit breaker to provide damping effect to over-voltage due to switching transients. It simply provides additional protection to the insulation/dielectric of the circuit breaker.

Answer / william wright

Closing resistors are also intended to allow shunting of
over-voltages power surges that cause that can damamge the
system protected.

Answer / k.prakashchandra

You mean the resistance connected in series with the
closing coil ? It is used to reduce the current in solenoid

1. for eg, capacitor is used for many purposes(it act as filter, oscillator, bypass capacitor, memory storage etc...) 2. Please tell me some example circuits for different uses of capacitor( whenever and whereever and however we used capacitor as a filter, oscillator tuning etc..) 3. similarly for inductor and resistors(it act as what?) and when and how we want to act as like that?, and how we can used these components depends upon our requirments with example circuits and explanation? design to act as these components depends
