Vernier Circuit Board 2

The Vernier Circuit Board 2 is a convenient platform for circuit labs, from basic series and parallel circuits to RLC circuits. Many components are provided for experimentation, and additional components can be added to expand the capability of this useful board.

SKU: VCB2 Category:


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.
