Using nodal analysis to predict the circuit behaviour.
measured value of v1 is 2.38v.
measured value of v2 is 4.37v.
Measurement datas:
We got the voltages measured accros 22Kohm and 6.8 kohm. V1=4.4241v, V2=2.4241v.
This is the voltage across the resistor when there’s not light. Our experimental value is 4.38 V, while our theoretical value is 4.42 V.
% difference: (4.38-4.42)/4.38*100%=-0.9%
