2 cards from this section. Quick, good the night before a test.
What is the unit of capacitance?
Think of the formula relating charge and voltage.
Explain what a dielectric does in a capacitor.
Consider the effect of an insulating material.
What does the capacitance of a parallel plate capacitor depend on?
Remember the capacitance formula C = (ε_0 * A) / d.
True or False: The electric field strength between the plates of a capacitor is uniform.
Think about the large area relative to the distance.
If a capacitor is charged to 50V with a capacitance of 25μF, how much charge is stored?
Use the formula Q = CV.
How would the capacitance change if the dielectric constant of a capacitor is increased from 2 to 5?
Consider the relationship between capacitance and the dielectric.
