What are the steps to find the capacitance of spherical or cylindrical capacitors?
- Find the electric field using Gauss's Law. 2. Calculate the potential difference using . 3. Use to find the capacitance.
For a parallel plate capacitor, what does 'A' and 'd' represent in the formula ?
A is the area of the plates, d is the distance between the plates.
What is the effect of increasing the area (A) of the plates in a parallel plate capacitor?
Increasing the area (A) increases the capacitance (C), as .
What is the effect of increasing the distance (d) between the plates in a parallel plate capacitor?
Increasing the distance (d) decreases the capacitance (C), as .
What is the effect of increasing the voltage (V) across a capacitor?
Increasing the voltage (V) increases the charge (Q) stored on the capacitor, as .
What is the effect of increasing the capacitance (C) of a capacitor?
For a given voltage, increasing the capacitance (C) increases the amount of charge (Q) the capacitor can store, as .
What is the effect of increasing the charge (Q) on a capacitor?
Increasing the charge (Q) increases the potential difference (V) across the capacitor, as .
