Question
Part B and Part D
Two capacitors arc in a circuit, connected in parallel as shown in the figure. The capacitances arc C_1 = 6.6 mu F and C_2 = 14.6 mu F. The battery carries a voltage of Delta V= 10.8 V. (a) Express the total capacitance C in terms of the two capacitances C_1 and C_2. (b) Calculate the numerical value of the total capacitance C in mu F. (c) Express the total charge on both of the capacitors Q in terms of capacitance C and the potential difference Delta V. (d) Calculate the numerical value of Q in mu C.Explanation / Answer
a) given that
c1 = 6.6 uF and C2 = 14.6 uF
total capacitance is C = C1+C2
b) C = C1+C2 = 6.6+14.6 = 21.2 uF
C) charge Q = C*V
d) Q = C*V = 21.2*10^-6*10.8 = 228.96 uC
