Question

Find the total capacitance (in uF) of this combination of series and parallel capacitors shown below. 19 uF 8.5 UF 0.90 uF

Answer 1

Ans: The capacitos elscuit is drawn below. Tauf 8.5 HF I ogleF In the above diagsam, 19hf and 8.5 MF Capacitors ase connected in parallelo let Cp be thels equivalent capacitance then Cp : 194f + 8.5 MF = 27.5MF li In capacitose parallel combination Ceq = 4 + 4 + Now the circuit takes following form- + an]. 27.5 MF .911F We see bath the series Capacitars ase connected Im Let c be their equivalent Capacitance them 1 - 94.5+ [: In series combination – de dį ceq 9

c Continued 블 (:9+27.5) 27.54.9 co 27.5X19 =:8715 ME 28.4 OR (= 872 [ Rounded off to three decimal places) Hence- Tatal capacitance 5.872 MF Ans
Problem is solved using formulas of equivalent capacitance inbseries and parallel combination of capacitors.
