A step-down transformer has 50 turns on secondary and 1000 turns on primary winding. If a transformer is connected to 
source, then what is output current of the transformer?
A
A
B
20 A
C
100 A
D
2 A
Text Solution
Verified by ExpertsThe correct answer is:
B
We know that,
where, V S = voltage across secondary coil
V P = voltage across primary coil 
N P = number of turns is primary coil 
and N S = number of turns in secondary coil 
Power in the secondary coil = Power in the primary coil
