  1. Capacitance C of a capacitor is defined as the ratio of charge Q to potential difference V. Which statement is correct?
  2. A capacitor has capacitance 50 μF and is charged to a potential difference of 12 V. Calculate the charge stored (in coulombs) on each plate.
  3. For a parallel plate capacitor with plate area A and separation d, the capacitance is:
  4. A parallel plate capacitor has square plates with side length 0.10 m separated by 2.0 mm. Calculate the capacitance in picofarads (pF). (Use epsilon_0 = 8.85 times 10^-12 C²/(N·m²))
  5. A cylindrical capacitor consists of two coaxial cylinders. The capacitance per unit length depends on:
  6. A spherical capacitor has inner radius a and outer radius b. Its capacitance is:
