Name two factors on which the magnitude of an induced e.m.f. in the secondary coil depends.
Advertisements
उत्तर
The magnitude of e.m.f. induced in the secondary coil depends on the following two factors:
- The ratio of the number of turns in the secondary coil to the number of turns in the primary coil (i.e., turns ratio).
- The magnitude of e.m.f applied in the primary coil.
