Unformatted text preview: ECE 201 Lecture 11 Source Transformations Linearity and Superposition + + Setting Source to Zero Rest of circuit + Let V s =0 Rest of circuit Voltage source: Current source: Rest of circuit Let I s =0 Rest of circuit replaced by short circuit replaced by open circuit Two-Terminal Networks • A two-terminal network is a network of circuit elements with only two terminals available for connection with other circuits • Examples of two-terminal networks Two-terminal network + + V-I Characteristic of Two-Terminal Networks The v-i characteristic of a two-terminal network is the voltage drop v across it expressed as a function of the current i through it ( using the passive sign convention ). Two-terminal network Two-terminal network To obtain the v-i characteristic by experiment: • Connect the two-terminal network to an independent current source with adjustable i • Measure v for different i • Plot the graph of v as a function of i • A resistor with resistance R • By Ohm’s Law, • v-i characteristic is a line through the origin V-I Characteristic of Resistors Slope R •...
