Vo = 12 volts (static)
Vo|t = 0+ = 12 volts (static) Analysis Assumptions and Modeling Notes
The problem is similar to VM206 except the coil is excited by an external circuit using the general circuit element.
In the circuit, the coil is modeled by a stranded coil circuit component that shares a common node with the coil
in the finite element model. The finite element model provides to the circuit the necessary coil resistance and
inductance to characterize the stranded coil circuit impedance. The nodes in the coil region are coupled in the
EMF and CURR degrees of freedom so that a single voltage drop (EMF) and coil current (CURR) are calculated.

A static analysis is run to obtain the coil resistance and inductance so that an analytical solution of the transient
response can be calculated and compared to the solution results. A transient solution to a step voltage excitation
is run for .01 seconds. The calculated c...
