SPSS has three different sets of commands for producing graphs. The easiest to learn and use are the oldest legacy graphing commands. They give you graphs with a default visual style (colors used, weight of lines, size of type, etc) that can be customized by hand.
Storing Energy in a Capacitor. The energy stored on a capacitor can be expressed in terms of the work done by the battery. Voltage represents energy per unit charge, so the work to move a charge element dq from the negative plate to the positive plate is equal to V dq, where V is the voltage on the capacitor.
Current. The transfer of charge (i.e. moving charge) is called current. More specifically electric current is the rate of flow of charge i.e. the amount of charge passing a given point in a circuit each second.The unit of current is the Ampere (A) and 1 Amp is therefore 1 Coulomb of charge passing each second.1 A = 1 C / s.ore specifically electric current is the rate of flow of charge i.e. the amount of charge passing a given point in a circuit each second.
