Hello!

Could anybody help me to form equations which describe RLC circuit? ---R1---L------ | | | e C R2 | | | ---------------

I need to form Simulink model(consist of integrators,derivatives) to find C current and R2 current. C and R2 are in parallel.

Thank you!

Thanks for reply!

I have already found first link, but my lack in electronics and math knowledge does not allow me to transform that equations. Could you help with transformation? I have the same circuit but in addition R in parallel with capacitor.

It's just a matter of knowing the impedance of each component and apply the voltage divider formulas http://en.wikipedia.org/wiki/Voltage_divider , also the Ohm law http://en.wikipedia.org/wiki/Ohm's_law
