Potential Difference
between two points
Always has polarity
(+/-)
Measure voltage in
parallel


The flow of electrical
charge through a
conductor or circuit
element
Current flow requires
a continuous path
Measure current in
SERIES

Electric circuits


Current flow requires a continuous path
Voltage can appear across an open circuit
11
Series Circuits

Current in Series circuits is the same
12
Parallel Circuits


Voltage in parallel circuits is the same
Va = Vb = Vc
