प्रश्न
On which type of current do transformers work?
Advertisements
उत्तर १
The transformer works on alternating current or A.C. current.
उत्तर २
No, they aren't suitable for use with direct current because, in the absence of a change in the magnetic field lines connected to the coils, no induced current can flow in the other coil.

The input and output voltage of a transformer are 220 V and 44 V respectively. Find: the turns ratio.
State the principle of a step-up transformer. Explain, with the help of a labeled diagram, its working ?
What is a transformer? On what principle does it work?
Explain the construction of transformer.
A transformer is essentially an a.c. device. It cannot work on d.c. It changes alternating voltages or currents. It does not affect the frequency of a.c. It is based on the phenomenon of mutual induction. A transformer essentially consists of two coils of insulated copper wire having different numbers of turns and wound on the same soft iron core.
The number of turns in the primary and secondary coils of an ideal transformer is 2000 and 50 respectively. The primary coil is connected to a main supply of 120 V and secondary coil is connected to a bulb of resistance 0.6 Ω.
