  3. Teaching Assistants • Anand Ambardar • David Pelster

  4. Agenda • Lab Safety (repeat) • Voltage • Current • Electric Circuits • Resistors • Color code

  5. Breadboards • Circuit construction techniques • Power Supply: 8102 Lodestar DC Power Supply • Virtual Instruments: Multimeter NI 4060

  6. Vocabulary • Electric Circuit • Voltage • Current • Parallel • Series

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

  8. Current: Amperes (A) • The flow of electrical charge through a conductor or circuit element • Current flow requires a continuous path • Measure current in SERIES • Direction is important

  9. Electric circuits • Current flow requires a continuous path • Voltage can appear across an open circuit

  10. Series Circuits • Current in Series circuits is the same

  11. Parallel Circuits • Voltage in parallel circuits is the same • Va = Vb = Vc

  12. Resistors • Carbon • Wire wound • Precision • Power Rating

  13. Breadboards • Power and Ground • Components • Rows and Columns

  14. Lodestar 8102 Power Supply • Dual 30 V 3 A • Independent • Series • Parallel • Dual ended (+/-)

  15. Lodestar 8102 Controls ON/OFF Mode Selector Volt – Fine and Coarse Current limiter Output Terminals Meters

  16. Lodestar 8102 Operation • Series • Parallel • Independent • Dual Ended • GROUND

  17. Multimeter Control Panel • Volts AC & DC • Current AC & DC • Resistance

  18. Summary • Lab Safety (repeat) • Voltage • Current • Electric Circuits • Resistors • Color code • Breadboards • Circuit construction techniques • Power Supply: 8102 Lodestar DC Power Supply • Virtual Instruments: Multimeter NI 4060
