two capacitor having capacitance of 10uf and 5uf are connected in series and this combination is connected in parallel with a 20v supplies this parallel combination calculate the charge on each capacitor .the voltage across the 10uc capacitor.

3 answers

C1 = 10uF, C2 = 5uF.

C = C1*C2/(C1+C2) = (10*5)/(10+5) = 3.33 uF.

a. Q1 = Q2 = C*V = 3.33 * 20 = 66.6 Micro Coulombs.

b. V1 + V2 = 20
V2 = 10uF/5uF * V1 = 2V1,
V1 + 2V1 = 20, V1 = 6.66 Volts.
Love u my dear teachers u have make the study easy for students and i got help with the question
Thank You Sir
