Question

Four capacitors are connected as shown below. If the potential difference between a and b is 12v:

a) Determine the equivalent capacitance Ceq?
b) Calculate the energy stored in the C4-capacitor?


please solve

Answer 1

a) 2[μF], b) 144 [J].

Step-by-step explanation:

`a. \ (1)/(C_(eq)) =(1)/(C_1+C_2+C_3) +(1)/(C_4); \ = > \ (1)/(C_(eq))=(1)/(2); \ = > \ C_(eq)=2 \ [ \mu F];`

`b. \ E=(CU^2)/(2); \ = > \ E=(2*144)/(2)=144[J].`
