The last step: the two 20 µF capacitors are connected in series. The equivalent capacitance is 10 µF. 16. An air-filled parallel-plate capacitor has a capacitance of 3 pF. The plate separation is then tripled and a wax dielectric is inserted, completely filling the space between the plates. As a result, the capacitance becomes 6 pF.
The three configurations shown below are constructed using identical capacitors OWhich of these configurations has the lowest overall capacitance? OA OB ос OAll three configurations have the same capacitance Submit (Survey Question) 2 Briefly explain your reasoning Submit
• C - Capacitance V= V a-V b - voltage difference • Capacitance, depends on the geometry of the two conductors (size, shape, separation) and capacitance is always a positive quantity by its definition (voltage difference and charge of + conductor) • UNITs: Coulomb/Volts or Farads, after Michael Faraday V Q C = CAPACITORS
