Investigating Voltage, Capacitance & Resonance in DC/AC Circuits

Click For Summary
The discussion focuses on an experiment investigating voltage variation across a capacitor in DC circuits and resonance in AC LRC circuits. The participant is seeking assistance in identifying sources of error for their experiment, having already noted random, systematic, and parallax errors. Other potential sources of error, such as measurement inaccuracies or environmental factors, are suggested but not detailed. The forum emphasizes the importance of self-initiated work before seeking help. Overall, the conversation highlights the collaborative nature of the forum while encouraging independent problem-solving.

Thread moved from the technical forums, so no Homework Template is shown
I have done an experimeny to investigate how the voltage across a capacitor, Vc varies as it charges and to find the capacitive time constant in a DC RC circuits and Study resonance in an AC inductor-capacitor circuit (AC LRC circuit).

I am now having trouble in writing the source of error of the experiment.I have wrote random error, systematic error and parallax error.Anthing else can i write?

Hello Janice, :welcome:

Here in PF we help students when thtey are stuck. We don't do the work for you. So you first embark on your own work, post (in a homework forum -- use the template) and then ask for help...

By the way: nice guide/instruction pdf !
 
Thread 'Correct statement about size of wire to produce larger extension'

Thread 'Correct statement about size of wire to produce larger extension'

The answer is (B) but I don't really understand why. Based on formula of Young Modulus: $$x=\frac{FL}{AE}$$ The second wire made of the same material so it means they have same Young Modulus. Larger extension means larger value of ##x## so to get larger value of ##x## we can increase ##F## and ##L## and decrease ##A## I am not sure whether there is change in ##F## for first and second wire so I will just assume ##F## does not change. It leaves (B) and (C) as possible options so why is (C)...
