I'm having trouble calculating inductance values in a transformer

[sdusheyko]

I have to figure out the two inductance values for a transformer; L2 and L1 where L1 is the inductance that sees the primary voltage and L2 is the secondary.

i'm working with the formulas;

n^2 = Z2/Z1 (8/1000)

roeL2>>Z2 (roe= angular freq= 1kHz)

n^2= L2/L1

basically i use this formulas to find L2, but it's in the tens of Henrys which doesn't make sense to me for a transformer that fits in my hand.

i carry out the computations for L1= .12 or something in that range, then plug it into the last equation and i get a massive value for L2. am i doing something wrong or are these values fine for theoretical computations?

thanks

.The inductance values you are calculating are not necessarily the practical values of the transformer. These values are calculated using theoretical formulas and are used to model the behavior of the transformer in a mathematical sense. The actual inductance values of a transformer can vary depending on the construction and size of the transformer. Therefore, these theoretical values should not be used as the actual inductance values in an application.
