OctoPrint Your Name _ Print Your Partners' Names _ _ You will return this handout to the instructor at the end of the lab period. The theoretical value of the capacitive time constant during charging is _ the theoretical value of the capacitive time constant during discharging while their experimental values are _. In the diagram above we display an RC circuit. When the switch is in position 1, the voltage source supplies a current to the resistor and the capacitor. Use a voltmeter to measure voltage drops. The theoretical functions for voltage and current versus time will be verified, as will the defining relation between capacitance, charge, and voltage. Unlike typical situations involving batteries and networks of resistors, in which steady-state behavior is quickly realized, RC circuits evince more readily observable exponentially-limited growth. ![]() As the current flows through the resistor, energy is dissipated in the form of light and heat, as you may recall from the lab. ![]() The outside case of the transformer is grounded but none of output terminals are.
