Question

calculate
a and b
effective capacitance between a and b

C1=C3=100πF
C2=C4=200πF
​

Answer 1

Answer:

150πf

Explanation:

C1 and C2 are in parallel so C' = C1+C2, 100 +200=300πF

C3 and C4 are also in parallel C" = C3 + C4, 100+200 =300πF

After this C and C' are in series so 1/C = 1/C' +1/C"

1/C = 1/300 + 1/300

1/c = 2/300

C= 150πF
