104. Suppose that the three capacitors in Figure 16.22 havethe following values:C1=0.15F,C2=0.25F, andC3=0.30F a. What is the equivalent capacitance of thisarrangement? b. how much charge will be drawn from the battery? c. What is the voltage across each capacitor? 104.

Explanation / Answer

a. What is the equivalent capacitance of thisarrangement? a. What is the equivalent capacitance of thisarrangement? Unfortunately I don't have access to Figure 16.22 but ingeneral: if capacitors are in series Ce = [1/C1 +1/C2 +..1/Cn) -1 if capacitors are in parallel Ce = C1 +C2 +...+ Cn - - b. how much charge will be drawn from the battery? since Q=CV just plug and play c. What is the voltage across each capacitor? b. how much charge will be drawn from the battery? since Q=CV just plug and play c. What is the voltage across each capacitor? The larger the capacitor the less voltage itwould have. Parallel capacitors it is easy. The seies is a bit tricky. Assume we have two capasitors inseries C1 and C2 then V1 = V C2 /(C1 +C2) and V2 = V C1 /(C1 +C2) Plese let me know if you have any further questions.
