Charging curve of a capacitor / charging and discharging of a capacitor
Article No: P2420201
A capacitor is charged by way of a resistor. The current is measured as a function of time and the effects of capacitance, resistance and the voltage applied are determined. Benefits Simple and very clear set-up: only few components required Further experiments in electricity and electronics can be performed with the equipment Tasks To measure the charging current over time: using different capacitance values C, with constant voltage U and constant resistance R using different resistance values (C and U constant) using different voltages (R and C constant). To determine the equation representing the current when a capacitor is being charged, from the values measured. Learning objectives Charging Discharging Time constant Exponential function Half life Even more accurate readings are possible when using the multimeter 07124-12.
