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.

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.

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.
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.
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 ...
The resistances of various DC conductors are determined by recording the current / voltage characteristic. The resistivity of metal rods and the contact resistance of connecting cords are calculated.
The electrical resistance of pure metals increases with increasing temperature. The correlation between voltage and current is to be measured using temperature-in- and dependent resistors. Determine the work and power of an incandescent bulb.
The Wheatstone bridge circuit is used to determine unknown resistances. The total resistance of resistors connected in parallel and in series is measured.
First Kirchhoff's laws are verified by measuring current, voltage and resistance in series and parallel circuits. The Wheatstone bridge circuit is used to determine unknown resistances more precisely.
