Chapters 19-20 WebLab#2“Capacitors”Ravikumar Ashok, Per. 4Part One*Go to the following website: http://www.phy.ntnu.edu.tw/java/rc/rc.html* Look at the electric circuit on the screen. The yellow dots represent electrons. The equally long, parallel vertical lines (labeled “C”) represent the capacitor. The unequally long, parallel vertical lines (labeled “V”) represents a battery attached to the capacitor by some wires (the other straight lines). The thick red line represents a switch, which acts sort of like a door. Clicking the switch “opens the door” and lets the battery charge the capacitor.* Click the switch and observe the how the current, the capacitor voltage, and the resistor voltage change over time. Recall that the voltage across the capacitor is proportional to the charge.* Click the switch again to “short circuit” the battery, allowing the electrons “stored” in the capacitor to leave. Observe how the current and voltages change over time.
This is the end of the preview.
