When two or more capacitors are connected in parallel across a potential differe

Question

When two or more capacitors are connected in parallel across a potential difference the potential difference across each capacitor is the same. each capacitor carries the same amount of charge. the equivalent capacitance of the combination is less than the capacitance of any of the capacitors All of the above choices are correct. None of the above choices are correct. Two capacitors, C_1 and C_2, are connected in series across a source of potential difference. With the potential source still connected, a dielectric is now inserted between the plates of capacitor C_1. What happens to the charge on capacitor C_2? The charge on C_2 decreases. The charge on C_2 remains the same The charge on C_2 increases When electric current is flowing in a metal, the electrons are moving at the speed of light. at the speed of sound in the metal. at none of the above speeds at nearly the speed of light. at the speed of sound in air. As more resistors are added in parallel across a constant voltage source, the power supplied by the source increases. decreases does not change. In the circuit shown in the figure, all they are identical which of the following is the correct ranking of the brightness of the bulbs?
