Voltage Transformation Ratio
The transformation ratio is defined as the ratio of the secondary voltage to primary voltage. It is denoted by K.
VOLTAGE
TRANSFORMATION RATIO
The transformation
ratio is defined as the ratio of the secondary voltage to primary voltage. It
is denoted by K.
From the above
equations of induced emf
E2/E1
= N2/N1 = K
• If N2>N1
i.e., K>1 then transformer is called step‒up transformer.
• If N2
<N1 i.e., K<1, then transformer is called step down
transformer.
Again
for an Ideal Transformer
Input (VA) = output
(VA)
V1I1
= V2I2 or E1I1 = E2I2
I2/I1
= E1/E2 = N1/N2 = 1/K
