Resistor type elements are often used in electrical
circuits. Consider the typical resistor element shown in Figure P2–23 with
nodes 1 and 2. One form of Ohm’s law says that the potential voltage difference
across two points is equal to the current I through the conductor times the
resistance R between the two points. In equation form, V = IR where I denotes
the current in units of amperes (amps) and V is the potential or voltage drop
in units of volts (V) across the conductor of resistance R in units of ohms ().
Use the method in Section 2.2 to derive the ‘‘stiffness’’ matrix relating
potential drop to current at the nodes shown as
