This discussion focuses on measuring capacitance using a basic multimeter that lacks a direct capacitance measurement feature. Participants detail a method involving an RC circuit, where a battery, resistor, and capacitor are used to calculate capacitance based on the time it takes for the voltage to drop to a specific percentage of the EMF. The capacitance range discussed is from 1 microfarad to 4000 microfarads, with an accuracy target of ±10%. Key considerations include the input resistance of the multimeter and the placement of resistors in the circuit for accurate time constant measurements.
PREREQUISITESElectronics enthusiasts, hobbyists, and students interested in practical methods for measuring capacitance without specialized equipment, as well as engineers looking to refine their circuit measurement techniques.
So are you going to put it together and see what values of C (using what values of R?) you can measure pretty accurately? That's the fun part of the project...ARoyC said:
You will need to experiment with a multimeter and some capacitors.ARoyC said:
