K=N2/N1=V2/V1
20=V2/12
V2=12*20
V2=240V
20=V2/12
V2=12*20
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

Ratio=N2/N1=V2/V1
V2=V1*RATIO
=12*20
=240V
V2=V1*RATIO
=12*20
=240V

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.

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.

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.

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

k = v2/v1; v1 = primary voltage = 12.
Turns ratio k = 20.
So 20 = v2/12 i.e., v2 = 240v.
Turns ratio k = 20.
So 20 = v2/12 i.e., v2 = 240v.

We know,
N2/N1=E2/E1=K
According to question
N2/N1=E2/12=20
=>20=E2/12
=>E2=12*20
=240V
N2/N1=E2/E1=K
According to question
N2/N1=E2/12=20
=>20=E2/12
=>E2=12*20
=240V
