1. Find the current in each resister in the circuit shown below. V, V, and . Hint: writing down the loop-current equations in terms of the symbols will give you most of the marks. 2. Determine the Thevenin equivalent circuit of the circuit shown below. Hint: determine and . 3. Consider the following circuit: 1. What is the Thevenin equivalent voltage?
2. What is the Thevenin equivalent resistance?
3. For a variable load resistance placed externally between the terminals A and B, plot the current through the load as a function of . Label the intercepts on both axes.
4. Sketch the current through a load resistance as a function of for the circuit shown below. Label both intercepts and the slope. 5. Find the voltage, , across the 3 load resistor for the circuit below by replacing the remaining circuit by its Thevenin equivalent. Hint: You can check your answer by direct analysis of the entire circuit. Doug Gingrich
