WebIn electronics, the voltage divider rule is a simple and most important electronic circuit, which is used to change a large voltage into a small voltage. Using just an i/p voltage and two series resistors we can get an o/p voltage. Here, the output voltage is a fraction of the i/p voltage. The best example for a voltage divider is two resistors ...

In a voltmeter there are 20 division between 0 and.5
WebThe voltage from point 3 to point 8 is a positive (+) 20 volts because the “red lead” is on point 3 and the “black lead” is on point 8. The voltage from point 8 to point 9 is zero, of course, because those two points are electrically common. WebApr 14, 2011 · Example I measured 13.8 volts, and with another meter in series with the voltmeter, I measured the current through the voltmeter at 1.2 micro-amps. 11.5 Meg Ohms. Most DMM's today are 10 Meg Ohms input impedance minimum, (even the free one from Harbor Freight) so the current measured will be in the micro-amp range. WebPurpose: To measure the internal resistance of practical voltmeters, and to examine the effect of a voltmeter’s internal resistance on the operation of a circuit it is monitoring. Theory: A practical voltmeter is modeled using a resistance, RM in parallel with an ideal voltmeter, as shown in the equivalent circuit below. Figure 1. ray white auckland city
