EE 2303

• Voltage and Current measurements

8
Vocabulary

• Electric Circuit
• Voltage
• Current
• Parallel
• Series

9
Voltage

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

10
Current Amperes (A)

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

11
Electric circuits

• Current flow requires a continuous path
• Voltage can appear across an open circuit

12
Series Circuits

• Current in Series circuits is the same

13
Parallel Circuits

• Voltage in parallel circuits is the same
• Va Vb Vc

14
Resistors

• Carbon
• Wire wound
• Precision
• Power Rating
