+10 Here we see a VOM configured as a voltmeter, used to measure voltage across resistor 3 in a three-resistor circuit: First, note how the meter’s test leads touch the resistor’s terminals, placing the meter in parallel with the resistor. A “parallel” network is defined as one having exactly two […]

+10 Electromotive Force (EMF) and Potential Difference If there is a surplus of electrons at one end of a conductor and a deficiency at the other end, a current flows. Certain devices create this difference in charge so current flows. These devices are sources of electromotive force. EMF is defined […]
