PRELABName: Colomba Cruz RiveraDate: 10/20/24Title of Experiment: RC DecayClass & Section: 246-202All lab partners:Bruna Mayen Joseph MunizPurpose:To study the discharge behavior of a capacitor and to learn how to determinethe time constant of an RC circuit.Physical Quantities and UnitsPhysical QuantitiesUnitsCapacitancefaradsChargeCoulombsVoltageVoltsKey Equations:Equation 1: The proportionality constant is called the capacitanceQ=CVEquation 2: measure the voltage across a capacitor than the charge𝑉=𝑉0𝑒^ −𝑡/RCSummary of procedure:We will verify that all circuit components are connected inseries and the lead from the positive outlet of the power supply is not connected to thecircuit. We will then charge the capacitor. We will read the voltage from the voltmeterevery 2 seconds and record the values in your notebook. (One person watches the timeand calls out intervals, one reads the voltmeter out loud and the third records thevoltage.) We will then graph the voltage vs. time.Hypothesis:The higher voltage results in a greater current flow.
