This lab was performed to show how an RC circuit charges and discharges under different circumstances. To charge the circuit a capacitor is used and is connected to a battery, which supplies the charge to the capacitor. To show how much charge is put into the capacitor, the equation Q=C*V is used. Where Q is the charge, C is the capacitance, and V is the applied voltage from the battery. Data Part 1: Part one uses a circuit that has a battery connected to a 1F resistor with a switch that was connected to 300KΩ resistance box then to a 220µF capacitor and a voltmeter, which then leads into the negative side of the battery. We are calculating the time it takes for the circuit to decay to zero (τ).
