Problem 4DQ

Since potential can have any value you want depending on the choice of the reference level of zero potential, how does a voltmeter know what to read when you connect it between two points?

Step-by-Step Solution:

Solution 4DQ Step 1: We use voltmeter to find the potential difference between any two points. When we use a voltmeter, we can see that there are two probes attached to the measuring instrument. One is red in colour and another is black. Usually the black probe of a voltmeter is connected to ground which is set as the zero potential reference. Thus when we connect between two points in a circuit, the one end is connected to ground and we can get the potential difference of that point with respect to the ground.
