Principle

In this experiment, the students should examine the effect filter capacitors and filter sections have on the direct and alternating current portions of a pulsating direct current. Since oscilloscopes are generally not used in student experiments, the students must note the brightness of the filament lamp used as a load resistor to determine how large the direct voltage portion is.

They can compare hum voltage based on the volume of the humming in the headphones. Furthermore, they can measure with the meter how much of it is alternating voltage. A capacitor is connected in front of the meter to filter out the direct voltage. Since the minimum alternating voltage measurement range of 10 V is too insensitive, we suggest to use a more sensitive alternating current measurement range of 30 mA.

Contact saftey due to puzzle blocks system
Corrosion-free gold plated contacts
Doubled earning sucess: Electric circuit diagram on top, real components can be seen unterside

Tasks

How can pulsating direct current be transformed into smooth direct current?

Using capacitors and coils, try to reduce the ripple of a pulsating direct current produced by rectification as much as possible.
