A low-loss transformer has 230V applied to the primary and gives 4.6V in the secondary.
Secondary is connected to a load which draws 5A of current. The current in the primary
is:
In a transformer, the number of primary coil and secondary coil are 5 and 4 respectively.
If 240 V is applied on the primary coil, then the ratio of current in primary and secondary
coil is:
The primary winding of a transformer has 500 turns whereas its secondary has 5000 turns
The primary is connected to an a.c supply of 20V,50Hz. The secondary will have an output of
A step-up transformer operates on 230V line and supplies a load of 2A. The ratio of
primary and secondary turns is 1:25. The current in the primary is:
