Answer to Question #327397 in Electricity and Magnetism for green

Question

For the network of capacitors shown, find the equivalent capacitance and the total charge when connected to a 36 V source. Note that C₁ = C₂ = 4.0 F and C₃ = C₄ = 6.0 F.

Answer 1

$C_{12}=C_1+C_2=8~F,$

$C_{34}=C_3+C_4=12~F,$

$C=\frac{C_{12}C_{34}}{C_{12}+C_{34}}=4.8~F,$

$q=CU=173~C.$
