Question

Please explain each step in the solution

6. Find the equivalent capacitance of the combination. Assume that Ci is 10 uF, C2 is 5uF and C3 is 4uF (2 marks)

Answer 1

we knowo thout Capacitors are connected in series then they gets equally charged +2..-8 +0.-879-8 sa G son replacing all capacito's by Cequivalent- Now, ceq = 0 Applying Kirchhoff's voltage dans :-8-8-8 +V=D so, vz. B[& te teken] And g = coqu

w, in parallel Combination, voltage drop across each Capacitor is same. & ♡ Geg - so, we can say that 8=8, +62 +63 Ceq r = cuterter itth E so, [ceq=C, tq te ] 7 the problem asked Now, > ( من d we com replace this circent as

in parallel I we com see that c, and ly are - Combination to each other, so equivalent of c, and ca. let G be equipalent, then, circut com be drown as city I Now, we can see that Cz and C are in series a combination. So, now equivalent of whole circuit be Ceq. - then. = 1+2 vt ce L = o te Со с. putting C2 = e,te then Geg = GB (6+6) then eq , + + 1

given c, zlour g=5.uf za 4MF cea = (4x10-6) (15 x 10-6) 19x10rb So, ceq = 3.15 ME capacitance of the - this is the required equivalent combination.
