A 12 volt automobile battery may be represented as an ideal voltage source in series with
a resistance (sometime referred to as the internal resistance of the battery). Resistance is
in units of ohms, which is denoted by the Greek letter Ω. A load resistor, R, is placed
across the terminals of the battery, as shown below.

Use SPICE (with voltmeters, ammeters, resistors, and .OP simulation) to determine:
a) The current Io through a short circuit (R=0 ohms) across the battery (print out
circuit picture with value in the ammeter)
b) The voltage drop, Vo , across a 20 ohm load (R=20 ohms) and current through the
load, Io (print out circuit picture with values in the ammeter and voltmeter).
c) The voltage drop, Vo , across a 2000 ohm load (R=2000 ohms) and current through
the load, Io (print out circuit picture with values in the ammeter and voltmeter).
You must hand in either a print out of each circuit (directly from B2Spice) used to obtain
the results for each part. Or you can use the &quot;copy circuit picture&quot; feature under the Edit
menu option and paste all 3 circuits onto a single page in MS word and then print out that
page. The meters should show the results on the circuit you hand in.
