What is critical resistance of the field circuit of a DC generator?
The value of resistance of shunt field winding beyond which the shunt generator fails to build up its voltage is known as " critical resistance at a given speed it is the maximum field resistance with which the shunt generator excite.
Why a dc shunt generator may fail to self excite?
If there is no residual magnetism in the field poles then there would be no flux too induce the initial voltage for self exitation
If one bulb fails and all the others turn off you are dealing with a?
A circuit of a series configuration.
When lights are wired such that if one bulb fails the entire string of lights goes out they are said to be wired in?
series
Is a parallel circuit brighter than a series circuit?
Both are same. Only thing it depends upon the incoming voltage. In series ciruity if one bulb fails, the ciruit continuity breaks . In case of paraleel circuit even if one bulb fails the circuit continuity will not get affected
When a shunt generator fails to build up the voltage then how to rectify the fault?
It fails to build up because self excited DC motor's armature have only one direction of rotation. So that if the poles of the armature are reversed, then this causes the reduction in the residual magnetism and eventually, it will stop.
What will happen when a SINGLE connection to one of the network hosts in a full mesh network fails?
Nothing should happen; that is reason you have fully redundant links, in case a link fails.
What can you do when a custody mediation is broken?
If mediation fails for any reason, then it falls to the judge to determine custody.
Why is profit important to businesses?
If there is no profit the business fails because thats the reason for the business in the first place. :-)
What can one do if their Dell touchpad fails?
If one's Dell touchpad fails and the machine is still in warranty, it can be sent off to the Dell service centre for repair. Otherwise, a private computer repair store would be able to help.
How do you use that in sentence?
When the gas machine that mows the lawn fails, the person who mows the lawn must push the non-gas mower.
What is critical resistance of the field circuit of a DC generator?
The value of resistance of shunt field winding beyond which the shunt generator fails to build up its voltage is known as " critical resistance at a given speed it is the maximum field resistance with which the shunt generator excite.
How does Nikola Tesla walk through lightning in the Prestige?
Tesla constructs a teleportation machine that resembles a Magnifying Transmitter, but the device initially fails to work. But the reality was that the machine creates a duplicate of any item placed in it, which appears some distance away. Remember that it is a fictional machine.
What is a theme statement for the time machine by hg wells?
Adventure never fails unless you stop exploring. or, Adventure goes on and on as long as you keep exploring.
How many clutches will a blue jay lay in a season?
Usually just one, unless the first attempt fails for some reason.
Does the bobbin go in clockwise or anticlockwis-sewing machine?
It depends on the sewing machine. They often have little arrows on the bit the bobbin goes in to help. Try looking at your manual or if all else fails, try it each way and see what works!
How do you use theoretical probability?
a machine has two parts the probability of failure of one parts in a given period of time is 0.06 the probability of failure of the other part in the same period os 0.08 what is the probability that the machine fails in that period of time ?
