The experiment aims to investigate the decay curve of charge/current when discharing a capacitor. Thanks! Can someone tablet some errors (better with improvement) or precautions when discharging a capacitor? The experiment aims to investigate the decay curve of charge/current when discharing a capacitor.
Measure the potential across a capacitor as a function of time as it discharges and as it charges. Fit an exponential function to the data. One of the fit parameters corresponds to an experimental time constant. This experiment features the following sensors and equipment. Additional equipment may be required.
Measure an experimental time constant of a resistor-capacitor circuit. Compare the time constant to the value predicted from the component values of the resistance and capacitance. Measure the potential across a capacitor as a function of time as it discharges and as it charges. Fit an exponential function to the data.
The rate of the decrease is determined by the product RC, known as the time constant of the circuit. A large time constant means that the capacitor will discharge slowly. In contrast, when the capacitor is charged, the potential across it approaches the final value exponentially, modeled by
As the charge flows, the charge q on the capacitor is depleted, reducing the potential across the capacitor, which in turn reduces the current. This process creates an exponentially decreasing current, modeled by The rate of the decrease is determined by the product RC, known as the time constant of the circuit.
where C is a proportionality constant known as the capacitance. C is measured in the unit of the farad, F, (1 farad = 1 coulomb/volt). If a capacitor of capacitance C (in farads), initially charged to a potential V0 (volts) is connected across a resistor R (in ohms), a time-dependent current will flow according to Ohm’s law.
