Terminal voltage and internal resistance of a voltage source

LP3.3.5.2

To carry out all experiments from this subject area, we offer you a complete set: CLICK HERE

Description

The students explore the dip in the terminal voltage of a battery under load. To do this, the load curve is recorded and the internal resistance is calculated on the basis of the measured current and the magnitude of the voltage dip.
