Voltmeter Schaltung. Working principle of voltmeter. Ein echtes voltmeter muss einen strom von der schaltung ziehen um das abstoßende magnetfeld zu erzeugen.
The chip senses the measuring input voltage as a parameter and compares it with reference every time the voltage crosses the certain part of reference the corresponding led glows. A voltmeter is connected in parallel with a device to measure its voltage while an ammeter is connected in series with a device to measure its current. The main principle of voltmeter is that it must be connected in parallel in which we want to measure the voltage.
At the heart of most analog meters is a galvanometer an instrument that measures current flow using the movement or deflection of a needle.
So it is a measuring instrument which measures the potential difference between the two points. In this case the meter movement s full scale current rating of 1 ma gives it a voltmeter sensitivity of 1000 ω v regardless of how we range it with multiplier resistors. The main principle of voltmeter is that it must be connected in parallel in which we want to measure the voltage. Es verwendet das prinzip des galvanometers die.
