Charging curve of a capacitor / charging and discharging of a capacitor

Article no: P2420201

Principle

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:
  1. using different capacitance values C, with constant voltage U and constant resistance R
  2. using different resistance values (C and U constant)
  3. 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.
