Question

In the figure the capacitances are C1 = 1.4 mu F and C2 = 3.4 mu F, and both capacitors are charged to a potential difference of V = 110 V but with opposite polarity as shown. Switches S1 and S2 are now closed. (a) What is now the potential difference between points a and b? What now is the charge in microcoulombs on capacitor (b) 1 and (c) 2? Number Units Number Units Number Units In the figure find the equivalent capacitance of the combination. Assume that C1 = 11.8 mu F, C2 = 4.21 mu F, and C3 = 5.67 mu F. Number Units Assume that a drop of mercury is an isolated sphere. What is the capacitance in picofarads of a drop that results when two drops each of radius R = 3.76 mm merge? Number Units the tolerance is +/-8% Click here if you would like to Show Work for this question

Explanation / Answer

Problem (11)

Ceq = 1/(1/(C1+C2) + 1/C3) = 1/(1/(11.8+4.21) + 1/5.67) = 4.19 uF
