Answer / jayesh vegad

Above ans.is absolutly
wrong.the of primary current
to secondry current is called
transformation ratio and the
ratio of primary turns to
secondry turns is called turn
ratio.

Answer / ameer

Turns ratio=Np/Ns
Transformation ratio=Ns/Np

Answer / fareeha azam

turn ratio=Np/Ns transformation ratio=Ns/Np

Answer / abiodun fadairo

Turns Ratio = Np/Ns

Transformation Ratio = Ip/Is

The product of Turns Ratio & Transformation Ratio = 1

Answer / vivek opjit

Transformation Ratio, R = IPri / ISec for a C.T.
and R = VPri / VSec for a P.T.
Turns Ratio, n = Nsec / NPri for a C.T.
= NPri / NSec for a P.T

Answer / anshuman

Turn ratio is the ratio of the number of turns in the primary winding to that in the secondary winding. But transformation ratio is the ratio of the primary to the secondary induced voltage. In an ideal transformer both are same but in a practical transformer there is a small difference between the two as the voltage(or current) are not transferred exactly as the ratio(inverse ratio in case of current transformation) of their turns ratio. But there is some error due to constructional limitations

Answer / vivek opjit

turns ratio= no. of turns in secondary/ no. of turns in primary &
transformation raio is depend upon operation of transformer i.e., if transformer is step up (N2>N1) than transformation ratio may be defined as
transformation ratio= N2/N1 also.

Answer / varaprasad

transformer ratio = secondry winding /primery winding

Is there a possibility to use such a treshold voltage for the NMOS part of a CMOS circuit that during the switching it will start conducting only after the PMOS part will be already closed, by this eliminating the leakedge current? Please note, I'm not asking about the well bias in standby mode, but about the "antileakedge" measures during normal operation.
