Here we have given turn ratio k=n2/n1=20.
primary voltage v1=12v.
secondary voltage v2=?
v2/v1=n2/n1
v2=(n2/n1)v1
v2=20*12=240v
primary voltage v1=12v.
secondary voltage v2=?
v2/v1=n2/n1
v2=(n2/n1)v1
v2=20*12=240v

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

K(Turning ratio)=V2/V1
V2=20*12
=240v
V2=20*12
=240v

E1/E2=N1/N2;
N1/N2=20; so E2=20*12=240volts
N1/N2=20; so E2=20*12=240volts

20 Ratio Mean Primary is 1turn and secondary turns are 20
So if secondry voltage is 12 V
So 20*12=240volts
So if secondry voltage is 12 V
So 20*12=240volts

v2/v1=n2/n1=k
here k=20,v1=12v
v2/12=20
v2=240v
here k=20,v1=12v
v2/12=20
v2=240v

Very simple::.
20*12=240.
20*12=240.

vs/vp=20
vs/12=20
vs=20*12
vs=240
vs/12=20
vs=20*12
vs=240

In transformer
t1/t2=v2/v1
20=v2/12,
v2=20*12=240
t1/t2=v2/v1
20=v2/12,
v2=20*12=240

Given ,k=20 (k=turns ratio)
and primary AC voltage is 12v,
We have to find secondary voltage=?,
as we know that, turns ratio=k=N2/N1,
K=N2/N1=20
(SECONDARY VOLTAGE/PRIMARY VOLTAGE)=v2/v1=v2/12,
THEREFORE,
N2/N1=V2/V1,
20=V2/12
V2=20*12=240
and primary AC voltage is 12v,
We have to find secondary voltage=?,
as we know that, turns ratio=k=N2/N1,
K=N2/N1=20
(SECONDARY VOLTAGE/PRIMARY VOLTAGE)=v2/v1=v2/12,
THEREFORE,
N2/N1=V2/V1,
20=V2/12
V2=20*12=240
