Part A: CAPACITANCE Step 1: Start the computer and allow it to complete its startup process. Step 2: Launch the PhET by clicking on the link provided above. After you click on the "play arrow", you should see two Icons; Capacitance and Light Bulb. Click on the Capacitance Icon. When the simulation opens, there will be a battery that is connected to 2 parallel plates. There is also a capacitance meter at the top of the s imulation, a voltage meter, and a control panel. The control panel should have plate charges, bar graph, and current direction selected. Click on the voltage meter and drag it out of its control panel and place it close to the parallel plates. Step 3: Notice that the battery has a variable voltage. Move the voltage slider up and down and observe the effect. Set the voltage slider so that 9 charges appear on each plate. Once a particular voltage is set, a corresponding amount of charge appears on each plate. a. ) To move charge from one plate to another, the battery must exert a force on that charge. The force must act through a distance. In other words, the force must do work on the charge. b.) The amount of a battery can do depends-in-part-on its voltage. Step 4: Take the electrodes on the voltage meter and connect them like the snapshot at the top of page 2
