Electrical capacity of earth is
(c) 711 µ F The electrical capacity of the Earth is approximately 711 microfarads (µF). This is based on the Earth acting as a large spherical conductor, and the value is derived from the Earth's surface area and the electric potential of the Earth.

When two capacitors charged to different potentials are connected by a conducting wire, what is not true?
When two capacitors at different potentials are connected by a conducting wire, charge redistributes until they reach a common potential. The charge lost by one equals the charge gained by the other, but potential change depends on capacitance. Some energy is lost as heat due to charge redistributioRead more

A condenser is charged to double its initial potential. The energy stored in the condenser becomes x times, where x = ……
The correct answer is (b) 4. The energy stored in a capacitor is given by U = (1/2) C V². When the potential V is doubled, the new energy becomes U' = (1/2) C (2V)² = (1/2) C × 4V² = 4U. Thus, the energy stored in the capacitor increases 4 times its initial value. For more visit here: https://www.tiRead more

When a number of capacitors are connected in parallel between two points, the equivalent capacitance
The correct answer is: (a) increases When capacitors are connected in parallel, their total capacitance is the sum of their individual capacitances: Ceq = C₁ + C₂ + C₃ +… This increases the overall capacitance, allowing the system to store more charge at the same voltage.
