Description: A Tektronix 2445 oscilloscope is used to display
charge and discharge times of a capacitor along with the voltage
across the resistor. Clearly demonstrates voltage drops across
capacitors and resistors
Instructions: Channels 1 and 2 are capacitance and resistance. Invert one of them, then push in the "Add" button nearby. This will show the square wave (in addition to the resistor and capacitor voltages).
3rd channel is trigger channel NOT the square wave; this is not needed, as we can trigger off channels 1 or 2.
Items Used: Oscilliscope, RC circuit apparatus
Notes: Resistance is adjustable as well as the pulse frequency on the box. Box requires external power supply. Camera use required for class to see. Math Description: None.
