WebThe video includes explanation of current sensitivity of MCG and practical demonstration to determine current sensitivity of moving coil galvanometer in the simplest way. Show more. WebAbout Transcript To convert a moving coil galvanometer to a voltmeter, we add a high series resistance, but why?. The high resistance causes most of the voltage to drop across it, leaving a small voltage drop across the galvanometer. This also ends up making the voltmeter have very high resistance. Ideal voltmeters have infinite resistance. eaton pkzm0 63 xtpr6p3bc1 https://trunnellawfirm.com
