Diodes as electrical valves

Principle

A diode only allows electric current to pass in one direction and blocks the other one to the current. It therefore acts as an electric valve. This enables alternating current to also be usable to pump charge into a capacitor.

Diodes as rectifiers

Principle

A diode only allows current to flow in one direction and blocks the flow of itin the other direction. So the current can flow only during a half wave through a diode in an alternating current circuit.

Tasks

Measure ...

Bridge rectifiers

Principle

Rectifying circuits with a single diode can only utilize one half wave of alternating current. The bridge rectifier solves this problem by having four diodes connected such that a current path is open for each halfwave.

Ohm's law

Principle

Our objective in this experiment is to find the connection between electric direct voltage and the direct current that it causes. Ohm's law will be verified and the values of the different resistors will be determined from the experimental results.

Warm-up time of an energy-saving lamp

Principle

How long does it take for an energy saving lamp to reach full brightness? Energy-saving lamps (compactfluorescent lamps) are increasingly replacing customary filament lamps. They have the disadvantage that they need a longer time until their light rea ...
