Hello,(adsbygoogle = window.adsbygoogle || []).push({});

I calculated the transient response of a weakly coupled transformer (M ≠ L1L2), for a heaviside step function input. I get a decaying oscillatory response, even though I didn't include any capacitance, can this be? If interested here is the angular frequency I get:

ω=[itex]\sqrt{\frac{R_{1}R_{2}-\frac{(L_{1}R_{2}+L_{2}R_{1})^{2}}{4(M^{2}-L_{1}L_{2})}}{M^{2}-L_{1}L_{2}}}[/itex]

I think the units come out right, which is always a good check
