Power Amplifier

Ce kit comprend un haut-parleur et des accessoires utilisés avec l'amplificateur de puissance Vernier pour étudier les ondes mécaniques et les ressorts. Le haut-parleur contient un disque métallique léger collé au cône du haut-parleur. Un poteau d'entraînement fixé à la plaque métallique vous permet d'entraîner des matériaux élastiques tels que des cordes et des ressorts.

The Go Direct Voltage Probe combines a wide input voltage range and high precision, making it an excellent choice for lab investigations of both AC/DC circuits and electromagnetism. Use this differential probe to measure the voltage in simple circuits, to study basic principles of electrochemical cells, or to investigate the resistivity of different metals. With a range of ±15 V, this system is ideal for use in “battery and bulb” circuits. Go Direct Voltage is capable of kHz sampling and mV resolution, so you can also use it to capture more difficult electric potentials, such as the electromagnetic field induced in a coil by a moving magnet. This single sensor can take the place of several voltmeters in your classroom. The Go Direct Voltage Probe can be used in a variety of experiments: Measure potential difference at various places in series and parallel circuits. Investigate Ohm’s law in simple circuits. Measure the voltage across a capacitor in RC and RLC circuits. Explore Faraday’s law and induced EMFs in a coil of wire. Specification: Input voltage range: ±15.0 V Maximum voltage on any input: ±15 V Typical resolution: 0.5 mV Power: Internal rechargeable battery or USB connection Connections: Wireless: Bluetooth Wired: USB Included: Go Direct Voltage Probe Micro USB Cable

Verwenden Sie den Frequenzgenerator, um Sinus-, Quadrat-, Sägezahn- und Dreieckswellen in einem weiten Frequenzbereich zu erzeugen. Verwenden Sie den Leistungsverstärker, um diese Wellen in RLC-Schaltungsexperimenten zu verwenden oder um den Leistungsverstärker-Zubehörlautsprecher für ein Stehwellenexperiment anzutreiben. Dieses Gerät erzeugt Wechselstrom mit bis zu 15 MHz in einer Vielzahl von Wellenformen und liefert optimale Leistung bei niedrigeren Frequenzen für jede Wellenform. In Verbindung mit dem Vernier-Leistungsverstärker können Schüler die Frequenzen einfach steuern, um die Resonanzfrequenz eines RLC-Schaltkreises zu bestimmen oder stehende Wellen auf einem String zu erzeugen.
