1. Given the current through R1 (180Ω) from each source indicated by IR1(V1) (17.864mA) and IR1(V2) (1.942mA), would the net current through the resistor be obtained by adding or subtracting these individual current contributions? Explain.

2. If R2 (220Ω) failed due to an overload and the resistor opened up, what voltage would you measure across R2 (220Ω). Should be VR2 in this case.

R1 = 180Ω

R2 = 220Ω

R3 = 390Ω

R4 = 470Ω

V1 = 5V

V2 = 12V
