Question

A transformer has 20 turn of primery and 100 turns of secondary if the two ends of the primary are connected to a 220 v d. c supply the voltage across the secondary will be what​

Answer 1

Answer:

Es = 11,000

Explanation:

Given the number of turns in primary coils Np    = 20

         and  

number of turns in secondary coils Ns = 100

Voltage across primary coil E p =220V

We know

 Ns / Np = Es / Ep

100 / 20 = Es / 220

50×220  = Es

Es =  11000 v
