MCAT Physics Question — Voltage Capacitance
- Jan 14, 2015
- MCAT Biology, MCAT Blog, MCAT Question of the Day
Under a certain applied voltage, which of the following variables effects capacitance?
A) dielectric constant, area of the plates, and density of the conducting material
B) dielectric constant and area of the plates
C) dielectric constant, area of the plate, and distance between the capacitor plates
D) electric field, distance between the capacitor plates, and area of the plates
This question is testing your understanding of capacitors and the factors that influence their capacitance. By definition, capacitance is equal to the following:
C = εA/d
Where, C is the capacitance, ε is the permittivity of space and the relative permittivity of the dielectric material between the plates, A is the area of the capacitor plates, and d is the distance between the two plates.
Thus, C is the best answer.
