Hi everyone,
I'm really terrible at RLC circuits etc, these are two problems I'm having trouble with. I have attached schematics of them.
The first circuit, it says use thevenins theorem, determine the I in the 15Ω resistor and the voltage Vab of the AC circuit. I know I am meant to use a delta star transformation to determine the thevenin impedance, but I just don't know where to start!
The second circuit says to use norotns theorem to determine the current in the 15Ω resistor of the AC circuit. Again I don't know why but when it comes to using capacitors and angles etc in circuits, i get confused!
Please someone help, a step by step guide to solving these circuits?
Thanks!
