Student 1D HOW YOUR WORK FOR PARTIAL TO FULL CREDIT pts.) Two capaciiors with charge Q and Cs with charge O that are connected i parallel, as shown in Figure. Which ones are correet? (a) The potential difference laVlis the same across each capacitor (b) The two capacitors can be replaced by a single equivalent capacitor Co with a total charge O supplied by the battery (c) The total potential difference across each capacitor is equal to the sum of potential differences across the individual capacitors (d) Charges on all plates have the same magnitude (e) Equivalent capacitance of a parallel combination of capacitors is always less than any individual capacitance AVI (5 pts.) Consider two metallic plates of equal area A-104 cm2 separated by a distance d-2.57 mm, as shown in Figure. The top plate carries a charge +Q while the bottom plate carries a charge-O. The charging of the plates with only air between the plates can be accomplished by means of a battery which produces a potential difference of 5.26 V. Find the capacitance of the system. (eo = 8.85 × 10-12 F/m) 2. 2.57 min- +0 104 em2 5.26 VExplanation / Answer
TRUE OPTIONS:
(a) The potential difference is the same across each capacitor.
(b) The two capacitors can be replaced by a single equivalent capacitor.
(d) Charges on all plates have the same magnitude.
False options:
(c) As option(a) is true, hence this option has to be false.
(e) In parallel combination, Ceq = C1+C2, so the equivalent capacitance increases and is more than individual capacitances.
