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
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
