Is there more current in the primary or secondary winding of a transformer?
The terms, 'primary' and 'secondary', describe how a transformer is connected and his nothing to do with which is the lower- and higher-voltage winding.The primary winding is the winding connected to the supply, while the secondary winding is the winding connected to the load. So, for astep-up transformer, the secondary winding is the higher voltage winding, whereas for a step-down transformer, the secondary winding is the lower voltage winding.For a loaded transformer, i.e. a transformer whose secondary is supplying a load, the higher-voltage winding carries the smaller current, while the lower-voltage winding carries the higher current.
Why would a transformer designed to be connected to an emf of amplitude 170V be damaged if connected to a dc emf?
Transformers can't be connected In DC because they are not designed to be. When connected to an AC supply, current will flow through the primary winding. This current produces an alternating magnetic flux in the core. This flux links the primary winding to the secondary winding, inducing a voltage in the secondary winding. The induced current in the secondary winding, then causes a back emf to the primary winding, which limits the current drawin in the primary winding. At no load (when the secondary of the transformer is open circuited), this is called the magnetizing current. If the primary winding was connected to the DC supply, flux would be produced in the core just like the AC example, but this flux would saturate the core and no back emf would be generated by the secondary winding. This results in the only resistance seen by the DC supply being the transformer DC resistance, which is very low. Thus excessive current will flow in the primary, which will eventually damage the winding.
What is shunt current and a armature current?
The terms 'shunt' and 'armature' apply to a particular type of d.c. motor, in which the field windings are connected in parallel with the armature windings. 'Shunt' is an archaic term for 'parallel', so the term 'shunt', in this context, means that the field winding is connected in parallel with the armature winding. The terms 'shunt current' and 'armature current', then describe the currents flowing in the shunt winding and armature winding, respectively.
The primary winding in a transformer is connected to the what?
The primary winding of a transformer is connected to the supply, while the secondary winding is connected to the load.
If the series field winding of your motor was connected directly across the 120 V dc supply a. What current would flow?
If the series field winding of a motor is connected directly across a 120 V DC supply, the current that flows through the winding would depend on the resistance of the winding itself, as per Ohm's Law (I = V/R). If the resistance of the winding is known, you can calculate the current by dividing the voltage (120 V) by the resistance (R). Without knowing the specific resistance value, the exact current cannot be determined.
How can you distinguish the primary from secondaty side on a transformer?
Whichever winding is connected to the supply is the primary winding; whichever winding is connected to the load is the secondary winding.
What are the primary winding and secondary winding of a transformer?
The primary winding is the winding connected to the supply, while the secondary winding is the winding connected to the load. The terms, 'primary' and 'secondary' are unrelated to voltage levels.
In a transformer what induces a current in the secondary coil?
The current flowing in the primary generates a magnetic field which induces a current in the secondary winding.AnswerNo current is induced into the secondary winding of a transformer. What is induced is voltage. Current will only flow in the secondary winding if it is connected to the load, and it is the load that determines the current, not the primary current.
What is winding transformer?
A winding is the name given each of the coils wound around the transformer's core. A basic transformer has two windings, termed the primary winding (connected to the supply) and the secondary winding (connected to the load).
How do you determine that the field curents in a compound generator are aiding or canceling each other?
To determine if the field currents in a compound generator are aiding or canceling each other, you need to consider the connection of the field windings. In a compound generator, the series field winding is connected in series with the armature, while the shunt field winding is connected in parallel. If the current in the series winding flows in the same direction as the shunt field current, they are aiding each other, enhancing the overall magnetic field. Conversely, if they flow in opposite directions, they are canceling each other, which can lead to reduced output voltage.
What is the current in star connection?
If a motor is connected in star, the current in the motor winding will be equivalent to the line current. If the motor is connected in delta, the current will be 1/sqrt(3) of the line current. If three phase CTs are connected in Delta, their secondary current will be sqrt(3) higher than the CT ratio implies by the line current.
How capacitor is connected in a table fan?
