Measure DC voltages Resistor LED circuit Alice voltmeter Dr. Mahmood A. Hameed ECSE Department Rensselaer Polytechnic Institute Intro to ECSE Build Circuit on Protoboard +5V voltage source from M1K CHA and CHB Voltage measurements


  1. Measure DC voltages Resistor LED circuit Alice voltmeter Dr. Mahmood A. Hameed ECSE Department Rensselaer Polytechnic Institute Intro to ECSE

  2. Build Circuit on Protoboard  +5V voltage source from M1K  CHA and CHB  Voltage measurements with respect to GND  Dual channel voltmeter (CA-V and CB-V)  GND connection to M1K 9 September M. Hameed 2020

  3. Experimentally determine voltage drop across each element  Voltage across R1  CAV – CBV  Voltage across LED  CBV – GND = CBV  Using these voltage measurements we can determine the current through the LED. (same as current through R1) 9 September M. Hameed 2020
