Question

A transformer without power loss contains 10000 turns in primary and 50 turns in secondary. The primary voltage is 240 V and strength of electric current is 0.1A. Calculate the voltage and current in the secondary.

Answer 1

Answer:

V = 12, I =2

Explanation:

hope it helps!!

Answer 2

Answer:

The Turns Rule is:

Ns/Np=Vs/Vp

Where,

Ns = number of turns on the secondary coil

Np = number of turns on the primary coil

Vs = voltage across the secondary

coil

Vp = voltage across the primary coil

So if number of turns on the primary coil is more than on the secondary coil, the output voltage will be lesser than the input voltage. This is called a step down transformer.

In this case, the turns ratio is 5:4.

Np/Ns=Vp/Vs;

That is, 5/4 = 220 / x .

X=5/220×4= 174Voltage
