2 cards from this section. Quick, good the night before a test.
Define capacitance and its unit.
Think about how much charge is stored per unit of voltage.
What is the formula for capacitance in a parallel plate capacitor?
What do A and d represent in this formula?
What is the unit of capacitance?
What does capacitance store?
True or False: A dielectric reduces the capacitance of a capacitor.
Does a dielectric help store more charge?
Design a circuit with capacitors of 10 µF and 20 µF in series. Calculate the total capacitance and the energy stored when connected to a 50V source.
Use the formula for capacitors in series, then calculate the energy.
