Here is a quote from my book that i don't completely understand:"Compared to the resistance being measured, the internal resistance of a voltmeter is designed to be very high so that the meter will draw little current from the circuit" I have a couple of questions on this. 1. If the voltmeter has high resistance, won't that resist the current and mess up the whole circuit?(like I read as an answer to someone's question on this site)How is this quote true? 2. What is the purpose of resistance?Why would you want to resist a current?
Re: Why does heavy resistance draw little current from a circuit?
