Unit Exam II: Problem #1 (Spring ’08) The circuit of capacitors is at equilibrium. (a) Find the charge Q 1 on capacitor 1 and the charge Q 2 on capacitor 2. (b) Find the voltage V 1 across capacitor 1 and the voltage V 2 across capacitor 2. (c) Find the charge Q 3 and the energy U 3 on capacitor 3. 12V C 3 = 5 μ F C 2 C 1 = 6 μ F = 12 μ F 10/3/2008 [tsl377 – 16/18]

(c) Find the charge Q 3 and the energy U 3 on capacitor 3. 12V C 3 = 5 μ F C 2 C 1 = 6 μ F = 12 μ F Solution: (a) C 12 = 1 6 μ F + 1 12 μ F « - 1 = 4 μ F , Q 1 = Q 2 = Q 12 = (4 μ F)(12V) = 48 μ C . (b) V 1 = Q 1 C 1 = 48 μ C 6 μ F = 8V , V 2 = Q 2 C 2 = 48 μ C 12 μ F = 4V . (c)
