Name ___________________________ ECE 240 – Quiz #4 February 18, 2010 For the circuit shown above: a. Find the Thevenin equivalent of the circuit to the left of the points a-b. b. Find the Norton equivalent of the circuit to the left of the points a-b. c. What is the value of R L that will result in maximum transfer of power? Short circuiting the voltage source and open circuiting the current source, we get the resistor
