  1. SERIES CIRCUITS

  2. SERIES CIRCUITS Series Circuit: • Current is the same • Total resistance is the sum of all resistors • One path for Current flow

  3. SERIES CIRCUITS Analogies – Water flowing through a pipe Instrumentation Ohmmeter – Test equipment used to measure resistance Power distribution in Series – Proportional to voltage drops

  4. SERIES CIRCUITS Voltage sources in series Aiding – Sources in the same direction ( Add) Opposing – Sources in opposite directions (Subtract)

  5. SERIES CIRCUITS • Kirchhoff’s Voltage Law – The algebraic sum of voltages in any loop equal zero. • Voltage dividers – A way to calculate voltage drops without knowing the current. • Interchanging series elements – Voltage drops change as components are interchanged.

  6. SERIES CIRCUITS Voltage Sources and Ground Double Subscript notation – First letter tells where positive test lead will be, second letter tells where ground or negative test lead will be. Single Subscript notation – Assumed to be measured in reference to ground

  7. SERIES CIRCUITS Loading effects of instrumentation Troubleshooting Parallel Circuits Opens – Current ceases to flow Shorts – Excessive current
