N2/N1 = V2/V1 = I1/I2 = Turns ratio.
:. V2 = 20x12 = 240V.
:. V2 = 20x12 = 240V.

n2/n1 = v2/v1.
So n2/n1 is given = 20.
Primary voltage is given = 12v.
Here,
n2/n1 = v2/v1.
20 = v2/12.
v2 = 20*12.
v2 = 240.
So n2/n1 is given = 20.
Primary voltage is given = 12v.
Here,
n2/n1 = v2/v1.
20 = v2/12.
v2 = 20*12.
v2 = 240.

V1/V2 = N1/N2.
Turns ratio=20 i.e. N2/N1 = 20.
Primary voltage = 12 Volt.
So, Secondary voltage V2 = V1*N2/N1.
= 12*20.
= 240 Volt.
Turns ratio=20 i.e. N2/N1 = 20.
Primary voltage = 12 Volt.
So, Secondary voltage V2 = V1*N2/N1.
= 12*20.
= 240 Volt.

Turn = N.
Given, Turn Ratio=N2/N1=20 and Primary voltage=V1=12V.
Secondary voltage=V2=?
According to formula, N2/N1 = V1/V2.
V2 = (N2/N1)V1.
= 20*12.
= 240V.
Given, Turn Ratio=N2/N1=20 and Primary voltage=V1=12V.
Secondary voltage=V2=?
According to formula, N2/N1 = V1/V2.
V2 = (N2/N1)V1.
= 20*12.
= 240V.

Solution:
Turns ratio(K) = 20.
Primary voltage = 12.
N2/N1 = V2/V1.
V2 = N2/N1*V1.
V2 = 20*12 = 240V.
Turns ratio(K) = 20.
Primary voltage = 12.
N2/N1 = V2/V1.
V2 = N2/N1*V1.
V2 = 20*12 = 240V.

As N1/N2 = V2/V1.
AND Turns ratio = 20 & V1 = Primary voltage = 12.
While V2=Secondary voltage=? so above equation is used as,
20 = V2/12 &
20*12 = V2 SO V2 = 240V.
AND Turns ratio = 20 & V1 = Primary voltage = 12.
While V2=Secondary voltage=? so above equation is used as,
20 = V2/12 &
20*12 = V2 SO V2 = 240V.

Turning ratio = n2/n1 = 20 .
Primary volt = 12v.
Sec. volt = ?
n2/n1 = v2/v1.
20 = v2/12.
v2 = 240v.
Primary volt = 12v.
Sec. volt = ?
n2/n1 = v2/v1.
20 = v2/12.
v2 = 240v.

We know that:
Turn ratio of transformer is define as the ratio of turns of the wire in the primary winding to the number of turns of the wire in secondary winding.
i.e Turn ratio = N1/N2.
Given: N1/N2 = 20.
Primary side voltage V1= 12 volt.
Secondary voltage V2 = ?
Hence according to voltage transformation ratio.
V2/V1 = N2/N1 = I1/I2 = K.
Or, V2/V1 = N2/N1.
Or, V2 = N2/N1*V1.
= 1/20*12.
= 0.6 volt.
