The resistor in the snubbing circuit is there to minimize the reverse EMF spike that occurs when a DC inductive load, such as a relay coil or other electromagnet is released. Opening the snubbing circuit will expose the driving circuit to high voltage transients that can damage it.
What else can I help you with?
Why is there a resistor on a 36v solenoid?
It reduces contact noise by reducing large voltage and current spikes as the relay is opened and closed, called a snubbing resistor. Before the age of solid state controllers, there were no resistors across the solenoids. The purpose of the resistor is to provide a charging voltage for the capacitors inside the solid state contoller. Without the resistor it would take several seconds for the (50,000 microfarad) capacitor to charge and the equipment to run. With the resistor the capacitors are charged while the solenoid is open and the equipment is ready to run at all times.
Why is there no effect on other branches in a parallel circuit when one branch of the circuit is opened or closed?
this is because the energy can still flow through the other branches.
How can a circuit breaker be made to work after it has opened?
put your dick in it
What happens when a switch in a series circuit is opened?
it prevents electricity to flow. i hope that is right
What will happen to the charges in a circuit when they travel through a source?
When the switch is opened, the charge will drop to zero.
Why one of the leads of resistor connected in electronic circuit is opened while measuring its resistance?
You open one of the leads of resistor connected in electronic circuit while measuring its resistance in order to not introduce error cause by other components in the circuit.

When is an electric circuit opened?
An electric circuit is opened whenever a part of it is not connected to anything.
What circuit protection device can be reset after it opens?
A circuit breaker is an overcurrent device that can be reset after it has opened.
What would make a heater just turn off 0n a 1998 ford 250 van?
Blower motor wire fell off blower motor? Blown fuse? Resistor pack opened (opening electrical circuit) Bad switch?

What happens when a switch circuit is opened?
When a switch is closed the path through the circuit is continuous.
Explain thevenin's theorem?
Thévenin's theorem for linear electrical networks states that any combination of voltage sources, current sources, and resistors with two terminals is electrically equivalent to a single voltage source V and a single series resistor R #wikipediaactually i will explain you the way to solve problems applying this theorem consider a large network and in that network assume any resistance R about which you are asked o find the current and voltage-drop. now follow the steps below carefully1. remove the specific resistor from the circuit (open the resistor) and find the voltage across both the points(or even parallel to both the points) where the resistor is opened this is called VTH (this is called thevenin's voltage).Also dont forget to open the current sources if present.2. now to calculate the effective resistance as seen from the opened resistor short all the voltage sources and open all the current sources. and assume an arbitrary voltage V in the place of the opened resistor find current through the branch by mesh analysis and the ratio of voltage and current gives you the effective resistance fo the circuit as seen from the opened resistor. this is called Rth (thevenin resistance).now , after getting the values of VTH,RTH construct a circuit in which the given resistance R and RTH arein series with the voltage source VTH , and the so called found current is the current flowing through R in the actual circuit
What allows an electric circuit to be opened or turned off?

What happens when a switch in a current is opened?
current through the switch become 0.and switch become a high value resistor.
