Capacitors

3. The SI unit of capacitance. 1 Farad is defined as 1 Coulomb of charge stored per volt of potential difference.
6. Time taken for charge/voltage/current to fall to approximately 37% of its initial value.
7. During discharge, charge, voltage, and current decrease by the same proportion in equal time intervals.
8. An electrical insulator that can be polarized by an applied electric field, placed between the plates of a capacitor to increase its capacitance.
10. The charge stored per unit potential difference across a capacitor.

1. Time taken for charge/voltage to rise to approximately 63% of its maximum value.
2. Total capacitance is the sum of individual capacitances. The potential difference across each is the same. This happens to what?
4. A measure of how easily a material can become polarized by an electric field.
5. Reciprocal of total capacitance is the sum of the reciprocals of individual capacitances. The charge stored is the same on each capacitor. This happens to what?
9. An electrical component consisting of two parallel conducting plates separated by an insulating material that stores charge, and consequently electrical potential energy.
