Voltage and Current Measurement
Vocabulary
Electric Circuit
 Voltage
 Current
 Series
 Parallel

9
Electric Circuits
 A set of electrical components
 Sources, Resistors, Inductors, Capacitors
10
Voltage: Volts (V)
 Potential Difference
between two points
 Always has polarity
(+/-)
 Measure voltage in
parallel
11
Current: Amperes (A)
 The flow of electrical
charge through a
conductor or circuit
element
 Current flow requires
a continuous path
 Measure current in
SERIES
12
Series Circuits
 Elements placed one after another
 VTotal = VA + VB + VC
 IA = I B = I C
13
Parallel Circuits
 Multiple elements connected to the same node
 VA = VB = VC
 ITotal = IA + IB +IC

Ohm's Circuit Law

Voltage is equal to
current times resistance
• V =I*R
• I = V/R
• R = V/I
