ENGR 210 Fall 2008 Homework #6 Due October 8, 2008 Thevenin and Norton equivalent circuits Problem 1 (a) Remove the 50 Ω resistor and determine the Thevenin equivalent circuit with respect to the terminals a,b (i.e., across the 50 Ω resistor) for the circuit shown above. HINT: determine the short circuit current and the open circuit voltage. (b) Now replace the 50 Ω resistor. What is the current i φ through the 50 Ω resistor? (b) An ammeter is placed in series with the 50 Ω resistor. The meter reads 10A. What is the series resistance of the ammeter? a b
