    Physics: Post your doubts here!

    Let me try: C=Q/V, and they tell you for a capacity of 30 micro Farads the max voltage is 6V. So substitute these values: 30=Q/6. Q=180. So now we've got the charge on one of the capacitors. In parallel the combined capacitance is 20, and they're asking for the max voltage, so plug these values...

    Yes, after you add 0.02, you have to take into consideration the other information they give you which is +-1 digit. Since it's asking for the maximum, you'd obviously use +1 digit. I know it's kind of confusing but I see no other explanation for this!

    1 complete wavelength=2pi rads 0.25 wavelength= 0.5 pi rads 0.5 pi = 90 degrees

    90 degrees I think.

    Physics: Post your doubts here!

    But isn't the resistance of C decreasing with voltage? Why would the PD through it be greater than in R? Also, isn't the current through R constant? Why would there be a 'curve' for R?
