EMT 1150 NOTES (ELECTRICAL CIRCUITS) SERIES DC CIRCUITS 5.8 INTERCHANGING SERIES ELEMENTS It is possible to swap the elements of a series circuit without impacting the overall resistance, current, or power to each part. 5.9 NOTATION Notation plays an increasingly important role in the ensuing research. Therefore, it is critical that we start examining the terminology used across the industry. Electrical and electronic devices are grounded for reference and health reasons, except for a few special cases. The assumption that voltage is a cross-variable that occurs between two points has led to a doublesubscription notation that determines the higher potential of the first subscript. If this is not the case, then the amplitude of Vab must be correlated with a negative sign. The single-subscription notation Va defines the ground voltage (zero volts) at point a. If the voltage is less than zero volts, then the magnitude of Va must be associated with a negative sign....
