4.1 Use superposition to determine the voltage V in the circuit below. The current U is an arbitrary value. 20 www + U ww 30 www 6.Q 1.0 ww 6V 4.2 For the circuit of problem 1, determine an input-output relationship between the current U and the voltage V. Plot the relationship between U and V, using U as the independent variable (e..g. U is on the horizontal axis.) For the circuit of problem 1, replace everything but the current source with its Thevenin equivalent circuit. Replace the current source in your Thevenin circuit and determine the input-output relationship between the current U and the voltage V. Does your result agree with the input- output relation you obtained in problem 2?
