Frequency Generator

Mit Hilfe der zweiten Experimentierplatine von Vernier kann mit einfachen elektrischen Schaltkreisen experimentiert werden. Die Platine ist bestückt mit Kondensatoren, Widerständen, einer LED, Schaltern, Batteriehaltern, einem Anschluss für die externe Spannungsversorgung, einer selbstrückstellenden Sicherung, Lämpchensockeln, Anschlussmöglichkeiten für weitere Bauteile und Anschlusspins, die den Anschluss von Krokodilklemmen vereinfachen. Description The Vernier Circuit Board 2 is a basic electricity lab on a board. The turret terminals for every component make it easy to connect basic series and parallel circuits, examine the behavior of different components, and investigate RLC circuits. The Vernier Circuit Board 2 includes 10 bulbs, a resettable fuse, three powering options, 10 alligator clip leads, terminal clips to add your own components, and pre-installed components. Installed Components R1 and R2–10 Ω resistors rated at 5 W R3 and R4–51 Ω resistors rated at 2 W R5 and R6–68 Ω resistors rated at 2 W R7–22 kΩ resistor rated at 1 W R8–47 kΩ resistor rated at 1 W R9–100 kΩ resistor rated at 1 W R11–4.7 kΩ resistor rated at 1 W C1–1 µF non-polar capacitor C2–10 µF non-polar capacitor 3 E-10 lamp sockets LED and 220 Ω current limiting resistor L1–5 mH inductor, with powdered iron core in a clip 1 kΩ linear potentiometer 85 dB buzzer SW2–single-pole, double-throw (SPDT) switch SW3–single-pole, single-throw (SPST) momentary switch The Vernier Circuit Board 2 can be used interchangeably with the Vernier Circuit Board in experiments included in Physics with Vernier and Advanced Physics with Vernier–Beyond Mechanics.

Use a Power Amplifier to drive a variety of loads, including speakers, lamps, small DC motors, and RLC circuits. The Power Amplifier can produce DC, sine, square, triangle, and sawtooth waveforms. The Power Amplifier allows you to drive loads with ±10 V and up to 1 A current. Utilizes internal feedback for accurate AC waveforms and DC levels. Can provide a steady, linearly-controlled DC output for driving loads like DC motors, and precise AC waveforms for driving things like speakers. Current-limited to protect against overload and shorting. Current monitor function allows you to log real-time load current with any Vernier interface. Class A-B Push-Pull Amplifier provides low distortion with good efficiency. Supports LabQuest as a standalone device or a computer with Logger Pro 3.8 or newer and a LabQuest, LabPro, or SensorDAQ interface. Important Note:The Power Amplifier creates no signal on its own. It depends on a signal source such as a LabQuest 2, Original LabQuest, LabPro, or other signal source. LabQuest Mini does not provide a signal source. Frequency range:DC to 15 kHz. Overall gain:10X Input impedance:10 kΩ. Included:Vernier Power AmplifierPower supply3.5 mm audio cable for LabQuest controlBTA cable for LabPro input and current sensingUser manual
