Electricity Experiment

In this topic, your group will have 3 experiments. These are:


1. ELE 01-01. Determining the capacitance of a plate capacitor - Measuring the charge with the electrometer amplifier

This relationship is investigated using a demount-able capacitor assembly with variable geometry. Capacitor plates with the areas A = 40 cm² and A = 80 cm² can be used, as well as various plate-type dielectrics. The distance can be varied in steps of one millimeter.

2. ELE 02-01 Measuring current and voltage on resistors connected in parallel and series

The experiment ELE 02-01 examines the validity of Kirchhoff’s laws in circuits with resistors connected in parallel and in series. The result demonstrates that two resistors connected in series have a total resistance R
while for parallel connection of resistors, the total resistance R is

 

3. ELE 02-02 Voltage division with a potentiometer

In the experiment  ELE 02-02, a potentiometer is used as a voltage divider in order to tap a lower voltage component U₁ from a voltage U. U is present at the total resistance of the potentiometer. In a no-load, zero-current state, the voltage component

can be tapped at the variable component resistor R₁. The relationship between U₁ and R₁ at the potentiometer under load is no longer linear.
