Vector Addition
A variety of mathematical operations can be performed with and upon vectors. One such
operation is the addition of vectors. Two vectors can be added together to determine the result (or
resultant). Observe the following summations of two v

Capacitors practice:
Capacitance refers to the ability of something to store charge. The more charge that can be
stored with less push from the battery, the higher the capacitance:
