Electric Circuit Element (CIRCU124) Input Listing: vm117.dat Test Case
The network shown below is that of an unbalanced bridge used in measuring resistance. With the circuit parameters as specified, determine the current Ia-b flowing in each branch (from a to b) and the voltage at each node. Figure 117.1 Electric Current Problem Sketch Material Properties
R2-1 = 20 Ω
R3-1 = 10 Ω
R2-3 = 9 Ω
R4-2 = 30 Ω
R4-3 = 90 Ω Loading

The branch resistance is implicitly input as the element area (real constant). A convenient geometric configuration
is assumed ( = 1 ft) and the material resistivity is taken as 1 ohm-ft (input as material property RSVX). The areas
are calculated from the relation: A = ρ /R, where A = area of element (ft2), = length of element (ft), ρ = resistivity
(ohm-ft), R = given resistance (ohm).
Node 1 is assumed to be the ground node for refere...
