- Relevant Equations
- Ohm's law, Kirchhoff law,

I tried solving the part (a), and got I =1.82 A for the current value using Kirchoff's law.

Next, I want to use Ohm's law to calculate the voltage at point a.

Va = IR

In this equation, will resistance R correspond to 4.4Ω or 8.8Ω?

How do you determine which resistance to use when solving this problem?

As for part B, I was able to calculate Ceq and Q through following works:

I am now trying to find the potential at point b with the switch open through equation

Vb = Q/c

Again, which value of capacitance, 0.48 µF or 0.36 µF, and why?

Thank you!
