Question 3: (20 points) In the circuit shown, assume that the negative terminal of the voltage source is connected to ground and let node 1 be the node connecting the current source, 2-resistor, 4-resistor, and 8-resistor all together. Apply the source-superposition method to determine:
a) The component of V due to the voltage source alone.
b) The component of V due to the current source alone.
c) The total voltage V due to both the voltage source and the current source together.
d) The power dissipated in the 2-resistor.
