They are also used for work holding and inspection on the shop floor. In some shop work holding applications‚ the accuracy would not need to be to the level of lab or inspection gage blocks. V-blocks are precisely square‚ and the V-groove should be in the exact center of the block. The prime purpose of a V-block is to

Conductors and Insulators of Electricity A major reason electricity works is because of conductors. First metal‚ water‚ tall trees and tall items are good conductors because lightning is attracted to them. These materials have many mobile electrons. Metal is an easy substance for lightning to travel through so metals are good conductors. However‚ rubber is a bad conductor because lightning bounces off of it. A bad conductor is called an insulator. An insulator has a few mobile electrons. It is

oscilloscopes may be used for such purposes as analyzing an automotive ignition system‚ or to display the waveform of the heartbeat as an electrocardiogram. Originally all oscilloscopes used cathode ray tubes as their display element and linear amplifiers for signal processing‚ (commonly referred to as CROs) however‚ modern oscilloscopes have LCD or LED screens‚ fast analog-to-digital converters and digital signal processors. Although not as commonplace‚ some oscilloscopes used storage CRTs to display
