Explain why cruciform shape is used in transformer core?
to reduce core reluctance..
The leakage flux of transformer depends on?
Actually it depends on the air gap between the core and the windings of the transformer. This is the reason why stepped core is used in medium and large transformers as it decreases the air gap between the windings and the core of the transformer.
What type of current must be used with a transformer?
DC current cannot be used in a transformer only AC will work. A transformer needs the continual build and collapse of the magnetic field to keep the iron core from reaching saturation. Only alternating current will transfer power through a transformer.
Why no load current in transformer small?
No load current is energizing current. This is effectively "lost" power, power used in the transformer to energize the core. It, therefore, should be small!
What is the difference between transformer and reactor?
A transformer is composed of two coils and wrapped around a core while a reactor is made up of one coil of wire. A transformer is used to increase or decrease the amount of current while a reactor is used to isolate circuits from a noisy background.

Oil filled transformer is usually used indoor or outdoor?
An oil filled transformer is usually used outdoors and a dry core transformer is usually used indoors.
The leakage flux of transformer depends on?
Actually it depends on the air gap between the core and the windings of the transformer. This is the reason why stepped core is used in medium and large transformers as it decreases the air gap between the windings and the core of the transformer.
How dc supply is given to transformer used in push pull amplifiers?
The dc is supplied via a centre-tap on the transformer. This ensures zero dc net flux in the transformer core, which enables a much smaller core to be used.
What types of wire are used in transmission lines?
Stranded aluminium, with a steel core.
What is core type and sell type transformer?
Core transformer and shell transformer - it has a one window. - it has a two windows. - less mechanical protection - better mechanical protection to the coils. to the coils. -windings encircles the core. - core encircles the winding. - cylindrical windings are used. - sandwich type windings are used. - it is easy to repair. - it is not easy to repair.
Why cant a 18V battery be used as the input of a transformer?
The transformer needs AC at its input. The battery provides DC.
CAN you able to use any other thing instead of iron core in transformer?
shell type core can be used
Can transformer be used 225 percent of capacity?
Yes, but not continuously and not for long. That transformer's core will saturate and get hot, possibly to the point of becoming a fire hazard.
What is the best material of the core of a transformer?
The core is responsible for the hysteresis losses in a transformer. These are the losses associated with the ease, or otherwise, by which the core is able to become magnetised in one direction, demagnetise and, then, remagnetise in the opposite direction. These days, the type of material used (variations on silicon steel) are about as efficient as possible.
