In a step-up transformer, in comparison with the secondary the primary coil has __

Draw a labelled diagram of a step-up transformer. Obtain the ratio of secondary to primary voltage in terms of number of turns and current in the two coils.

In a step up transformer, if ratio of turns of primary to secondary is 1:10 and primary voltage si 230 V . If the load current is 2A . Then the current in primary is

In a transformer, the ratio of the number of turns in the secondary coil to that in the primary coil is 10:3. Such a transformer is called_______transformer.

In a step-up transformer the turn's ratio is 10. If the frequency of the current in the primary coil is 50 Hz then of the frequency of the current in the secondary coil will be

Compare a step-up transformer with a step-down transfonner bass on the number of loops in the primary and secondary coils.
