Flux is produced in both AC and DC systems, but the nature of the flux differs. In DC circuits, the magnetic flux is constant, as the current flows in one direction. In AC circuits, the magnetic flux changes direction and magnitude periodically, resulting in a time-varying magnetic field. Thus, while both types of current can produce flux, AC generates a dynamic flux due to its oscillating nature.
What else can I help you with?
Why don't we supply to DC to the transformer?
When we give d.c supply to a transformer the primary winding will burn because constent flux will be will be produced which doesnt link with secondary so max current will circulate on primary winding only
Why is rate of change of flux linking primary and secondary coils the same?
The 'rate of change' applies to the flux itself, and has nothing to do with it linking the primary and secondary windings. There is only one flux, so of course the rate of change is 'the same'.
Can a shunt generator build up its voltage without residual magnetism?
no...because before producing voltage needed to connect the generator to the grid then after it will produced voltage.AnswerYes, but only if you have an external d.c. supply to supply the field windings. Such machines are called, 'separately-excited'.
Why do transformers work only work on an AC supply?
Transformers only work on ac supply because it principle is mutual induction. DC supply has constant magnitude whereas AC has alternating magnitude. so we can step up or step down current/voltage in transformer in ac only.
Why is dual supply used for op-amp?
Dual supply arrangement allows for the output voltage to swing both above and below zero volts, and also gives an output of 0V when there is no voltage difference between the two inputs. An op amp can only amplify a signal to its values in the supplied range. If you want to amplify a signal with negative values then you need a negative supply.
Why transformer do not operate with DC?
Transformer works with varying flux. DC won't create it. Only AC produce varying flux.
What is the function of the iron core in a transformer?
The iron core is there to provide a path for the magnetic flux to link both the primary and the secondary with as little flux as possible linking only one of the windings. The cross-section area of the core determines how much magnetic flux there is, because transformer iron has a fixed maximum flux density, usually 1 Weber per square metre. The amount of flux determines how many volts per turn there are on both windings.
Why don't we supply to DC to the transformer?
When we give d.c supply to a transformer the primary winding will burn because constent flux will be will be produced which doesnt link with secondary so max current will circulate on primary winding only
How much uranium can the flux capacitor hold?
The flux capacitor is now only a phantasy. Flux capacitor will not work with Uranium. It has to be Plutonium.
Difference between mutual flux and leakage flux?
when a current flow through the coil then flux produced around the coil . if the flux linked same produced coil only then the flux is said to be leakage flux. flux produced by one coil ,but linked with another coil then the flu is said to be mutual flux.
Difference between leakage flux and mutual flux?
when a current flow through the coil then flux produced around the coil . if the flux linked same produced coil only then the flux is said to be leakage flux. flux produced by one coil ,but linked with another coil then the flu is said to be mutual flux.
Will a device that requires a 1.3A power supply work with a 500mA supply?
No, a 500 mA supply can only produce a half amp maximum without going into an overload condition.
In transformer core flux depends on voltage whereas leakage flux depends on current?
In a Transformer, Core flux is the difference of primary flux and Secondary flux which are opposite to each other in direction. There difference is equal to the no load flux at all loads. So, some of primary flux passes through the core and remaining becomes leakage flux (Because Secondary flux forces it to get out of the core). Same is the case with Secondary flux. Now, flux is directly proportional to Voltage and Current. When Current increases due to increased load (and voltage remains same): Then both primary and secondary flux increase. Because both of them increase, so there difference remains same. And all remaining flux is forced out. Hence leakage flux increases with current, but Core flux remains constant. When Primary Voltage is increased: Then only primary flux increases. So difference of this new increased primary flux and previous same secondary flux increases. Hence Core flux increases with voltage, But leakage flux does not. That's how In transformer core flux depends on voltage whereas leakage flux depends on current.
Do plants supply us with both carbon and oxygen for your bodies with energy?
No they only supply us with oxygen,CO2
Does only 1 testical produce sperm?
If both are healthy, both will be producing sperm.
Scarcity exists because there is a limited supply of?
Scarcity exists because we have unlimited wants and only a limited supply of resources to produce goods and services that satisfy our wants
Would supply increase if there is an increase in input prices?
If the price of one of the for factor of production increase, it would DECREASE the supply since for the same amount of money, you can only produce less of the same good (because it costs more to produce one of it.)
