Electrostatic Potentials and Capacitance
268024
Three identical capacitorsare connected together differently. For the same voltage to every combina-tion, the one that stores maximum energy is
1 the three in series
2 the three in parallel
3 two in series and the third in paralle with it
4 two in paralled and the third in series with it
Explanation:
Electrostatic Potentials and Capacitance
268026
Two identical capacitors are joined in parallel, charged to a potential \(\mathrm{V}\), separated and then connected in series i.e., the positive plate of one is connected to the negative plate of other.
1 the charges on the free platesare enhanced
2 the charges on the free platesare decreased
3 the energy stored in thesystemincreases
4 thepotential differencebetween thefreeplates is \(2 \mathrm{~V}\)
Explanation:
Electrostatic Potentials and Capacitance
268027
Two parallel plate air capacitors are constructed, one by a pair of iron plates and the second by a pair of copper plates of same area andsamespacings. Then
1 the copper plate capacitor has a greater capacitance thantheiron one
2 both capacitors will have equal non zero capacitances, in the uncharged state
3 both capacitors will have equal capacitances only if theyare charged equally
4 the capacitances of the two capacitors are unequal even they are unequally charged
Explanation:
Electrostatic Potentials and Capacitance

Select correct statement for a capacitor having capacitance\(C\), is connected to a source of constant emf \(E\)
1 Almost whole of the energy supplied by the battery will be stored in the capacity, if resistance of connecting wire is negligibly small
2 Energy received by the capacitor will be half of energy supplied by the battery only when the capacitor was initially uncharged
3 Strain energy in the capacitor must increases even if the capacitor had an initial charge
4 Energy stored depends on type of the source oferff
