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. Benefits - No additional cable connections between the building blocks needed - clear arragned and quick setup
- 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. Scope of delivery |
