1:29 Back Rec05-Capacitance·p.. PHYS 21 2 RECITATION EXERCISE 2: CAPACITORS IN SERIES AND PARALLE . Two charged capacitors of different capacitance C and Ca ane in garaliell as depicted in the image ntwhy ot? below. A battery maintains a constant voltage across each carWharcam you say about the charge 0s and Qa7 Are they the same Battery with Battery with fixed 6. What is the equivalent capacitance Ca for the arrangement in parallel? Whtwould be Q and Av for the equivalent capacitor? We are looking for a reasoning not jnt a formla Dashboard Calendar To Do Notifications Inbox

Explanation / Answer

Capacitance in parellel net capacaucapa,

Ceq= C1+ C2

Concern to the charge stored in capacitor, for constant value of voltage different value of capacitance stored different value of charges

Charge stored in C1,

Q1= Q* C1/(C1+C2)

Charge stored in C2

Q2= Q* C2/(C1+C2}

============

For series combination

Equivalent capacitance given by

Ceq= (C^-1+ C^-1)^-1

As the circuit is in series so the current through both of them is same.

Q1= Q2

Voltage across C1,

V1= Q1/C1

Volatge across C2

V2= Q2/C2

===============

Comment in case any doubt.. good luck
