Unformatted text preview: upled Thermal-Electric Line Elements (LINK68) 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 Vo = 100 volts ANSYS Verification Manual . ANSYS Release 9.0 . 002114 . © SAS IP, Inc. 1–261 VM117 Analysis Assumptions and Modeling Notes 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...
