Capacitance With DielectricEasyQuestion 31542

Question

Inserting dielectric K between plates (voltage source connected) changes capacitance by factor:
  1. A
    1/K
  2. B
    K
    Correct
  3. C
    K²
  4. D
    √K

Correct answer

K

Explanation

C = Kε₀A/d. With voltage fixed, capacitance increases by K and more charge is drawn from the battery.
