resistance looking into the interconnect terminals. This is the Thevenin resistance. Step two: Find the open circuit voltage, i.e. the voltage at the interconnect terminals if no
load is connected. This is the Thevenin voltage. Step three: Use the results from steps t and 2 to ﬁnd the output voltage by voltage

Version E statics 2. 3. Write a text input ﬁle to simulate this circuit with SPICE. 3mA . Step One: Pick one node as the reference node and label it with a zero. Any node can be
used for this purpose.
Step Two: Identify the remaining nodes in this circuit and number them. Step Three: Write a SPICE input ﬁle corresponding to your node labels. Recall that
independent voltage source names start with V, independent current source names start with an I, and resistor names start with an R. Also remember to include a title and the
.END statement. So 7 lines are required. 1 was ‘t Warsaw a 2. 113$ e t 3M 3. V3 2. i t}
