Given that N2/N1 = 20.
V1 = 12.
V2/V1 = N2/N1 = 20.
So V2 = 20*V1.
= 20*12.
= 240.
V1 = 12.
V2/V1 = N2/N1 = 20.
So V2 = 20*V1.
= 20*12.
= 240.

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

N2/N1=V2/V1
Here N1=1,N2=20
V1=12;
So V2 = N2*V1
V2 = 20*12
V2 = 240v
Here N1=1,N2=20
V1=12;
So V2 = N2*V1
V2 = 20*12
V2 = 240v

V2/V1=N2/N1=I1/I2=K (TURNS RATIO).
SO V2/V1=K.
V2/12=20.
V2=20*12=240V.
SO V2/V1=K.
V2/12=20.
V2=20*12=240V.

We know,
V1/V2=T1/T2=A2/A1.
Hear T1/T2=20, T1=12,
So V2=12*20=240V.
V1/V2=T1/T2=A2/A1.
Hear T1/T2=20, T1=12,
So V2=12*20=240V.

Turns ratio :a=V2/V1.
then 20=V2/12,
V2=20*12=240,
So, V2=240v.
then 20=V2/12,
V2=20*12=240,
So, V2=240v.

Transformer ratio(K) = n2/n1,v2/v1=20.
So v2/v1 = 240/12 = 20.
So v2/v1 = 240/12 = 20.

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

Very simple.
v2 = v1*turn ratio.
So, the answer is 240 V.
v2 = v1*turn ratio.
So, the answer is 240 V.
