Experiment 13 - Discharging Battery II
What changes, when the Battery discharges?
In order to find out leave the circuit from the last experiment
connected for 10 minutes. Then disconnect the battery from the load circuit,
give the battery a few minutes to "rest"
and repeat the measurements.
At the battery
you measure a voltage
U0 = 8.8 V.
through the load circuit is only I = 0.62 A.
Hence you calculate an increased internal resistor
Measuring the voltage U0 of the slightly discharged battery without a load circuit.
Measurement of the current I in a load circuit.
In the next step you discharge the battery almost completely...
