If there is an $RLC$ circuit where some components are in series with one another and some components are in parallel with one another, how does the total impedance of the circuit is calculated?
I understand that the components that are in series will have their current in phase, while those that are in parallel will have their voltage in phase. All these different phases make me dizzy to operate on the circuit. How to approach these kinds of questions and are there any advices for students who are new to this concept?
My senior told me to use second-differential equation to solve it, but since I haven't learned that, my teacher told me to use phasor diagram to solve these kinds of questions.
