Previous Next Coil in Liquid Nitrogen # 5D20.10
Description: A coil of nickel wire is lowered into liquid nitrogen. The resistance of the coil is measured with a digital multimeter. It drops from around 3 ohms to 1.2 ohms. The digital multimeter is displayed on a television screen using the VideoFlex camera. Parts: LN2, Nickel coil, digital multimeter, VideoFlex camera, television. Quant. in Demo Room: 1 Demo References The Video Encyclopedia of Physics Demonstrations Disc 17-21 A copper coil in series with a battery and lamp is immersed in liquid nitrogen. Sutton H-103 A lamp glows brighter when a series resistance coil is immersed in liquid air.
