10 | Characteristic of a PV panel |
Description | A photovoltaic panel consisting of 21 cells has been exposed to sunlight (three different conditions of irradiation). For each irradiation, the load resistor has been varied. For each value of the load resistance, voltage across and current through the resistor have been measured. |

| 11 | Electric model of a windkessel |
| Description | An electric circuit is built consisting of a capacitor, two resistors, and a diode. The circuit models a (hydraulic) windkessel pump, where the pump is represented by a power supply (voltage source) whose voltage is changed rythmically. The voltage across the capacitor is measured. |
