Thank you for the quick reply. Yes, it is a bit confusing. If you look at the picture (example 2), should I first calculate the part-impedances, then add them using the first equation in order to achieve the total impedance? Thanks ehild

Homework Statement Hello again! We have been given a couple of more advanced problems where the components are placed in series parallely. Check the image, the question is regarding what equation to use, in order to calculate the total impedance of the circuit. Homework Equations I...

No worries, if it makes you feel any better I felt that the frequency and peak voltage was missing as well. As you're saying omega is important.

Many, many thanks! It really makes sense when you put it like that. Grateful for the quick and understandable answers!

Glad to hear that, we have used complex numbers in math but have not applied them to Physics yet. But how does one come to the equation: (1/Z)^2=(1/R)^2+(1/XL-1/XC)^2? Considering how the equation looks I would say that they relate to each other by a right angle triangle. How come? Is...

Hi Tim! Thank you The frequency is not given, would it be to any use? We know the resistance and reactances plus the total current, is that not sufficient?

Homework Statement A parallel RLC circuit with every component in parallel. The resistance is 120 Ohm, the reactanse over the capacitor is 150 Ohm and the reactanse over the inductor is 70 Ohm. The total current is equal to 100mA. Calculate the current passing through the inductance...
