Which of the following statements are true for the circuit shown in figure P5.8

Question

Which of the following statements are true for the circuit shown in figure P5.8 of the book (page 217)? You do not need to solve the circuit to answer this question, just apply linearity and superposition. A statement is considered true only if it is true regardless of the value of the resistors.

1.- If the value of voltage source V1 doubles, the output voltage Vout will also double

2.- If the value of both voltage sources V1 and V2 doubles, the output voltage Vout will also double

3.- If the value of all sources V1, V2, I3, I4 doubles, the output voltage Vout will also double

4.- If the value of all sources V1, V2, I3, I4 increases by 1 unit (voltage sources increase in 1 volt and current sources increase in 1 ampere), the output voltage Vout will also increase one volt

5.- The current through resistor R2 will remain constant, even if the voltage sources V1 and V2 change

6.- The power dissipated by resistor R3 is the sum of the powers dissipated when each source is considered independently while the others are set to zero (voltage sources are replaced by a wire and current sources by an open circuit).

The answers can be one of the following:

Only 3 is true

Only 3 and 5 are true

Only 4 and 6 are true

Only 6 is true

None of the above
