How to Use a Voltmeter: 12 Steps (with Pictures)
How to Use a Voltmeter: 12 Steps (with Pictures)
Principles of electricity/Voltage
Taking a measure from this to either battery terminal, we find a reading of 4.5 volts, or half the total voltage. Measuring identical resistances in series (daisy-chained resistances) should show that the value of each voltage measure is the value of the source (or total; 9V) divided by the number of identical resistances (in this case, 2 ...
