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.
Be able to compute how much energy is stored in an electrical storage device like a battery or a capacitor. 1  The voltage across the device is a measure of the energy-in joules-that a unit charge-one couloumb-will dissipate when it flows through the device.n other words, the power flowing into the battery is: P = - Vb Ir = - 12 * 0.5 = - 6w. 1  The power flowing into the battery is negative! 2  The power flowing out of the battery is positive! 3  And, it makes sense because we know the battery supplies power. 4  Batteries are often rated in ampere-hours (or milliampere-hours) and an ampere-hour is really a ...
