Internal resistance and matching in voltage source
Principle: Both the terminal voltage of a voltage source and the current depend on the load, i. e. on the external resistance. The terminal voltage is measured as a function of the current and from it the internal resistance and no-load voltage of the voltage source are determined and the power graph plotted.
Tasks:
1. To measure the terminal voltage Ut of a number of voltage source as a function of the current, varying the external resistance Re, and to calculate the no-load voltage U0 and the internal resistance Ri.
1.1 Slimline battery
1.2 Power supply
1.2.1 Alternating voltage output
1.2.2 Direct voltage output
2. To measure directly the no-load voltage of the slimline battery (with no external resistance) and its internal resistance (by power matching, Ri = Re).
3. To determine the power diagram from the relationship between terminal voltage and current, as illustrated by the slimline battery.
