Branch-current method A technique for determining the
branch currents of a multiloop network.
Bridge network A network configuration typically having a
diamond appearance in which no two elements are in series
or parallel.
Current sources Sources that supply a fixed current to a network
and have a terminal voltage dependent on the network
to which they are applied.
Delta (D), pi (p) configuration A network structure that
consists of three branches and has the appearance of the
Greek letter delta (D) or pi (p).
Determinants method A mathematical technique for finding
the unknown variables of two or more simultaneous linear
equations.
*53. Using Y-D or D-Y conversions, determine the total resistance
of the network of Fig. 8.127.
SECTION 8.14 Computer Analysis
PSpice or Electronics Workbench
54. Using schematics, find the current through each element
of Fig. 8.104.
*55. Using schematics, find the mesh currents for the network
of Fig. 8.111(a).
*56. Using schematics, determine the nodal voltages for the
network of Fig. 8.117(II).
Programming Language (C��, QBASIC, Pascal, etc.)
57. Given two simultaneous equations, write a program to
solve for the unknown variables.
*58. Using mesh analysis and determinants, write a program
to solve for both mesh currents of the network of Fig.
8.26 (for any component values).
*59. Using nodal analysis and determinants, write a program
to solve for the nodal voltages of the network of Fig. 8.44
(for any component values).
Mesh analysis A technique for determining the mesh (loop)
currents of a network that results in a reduced set of equations
compared to the branch-current method.
Mesh (loop) current A labeled current assigned to each distinct
closed loop of a network that can, individually or in
combination with other mesh currents, define all of the
branch currents of a network.
Nodal analysis A technique for determining the nodal voltages
of a network.
Node A junction of two or more branches in a network.
Wye (Y), tee (T) configuration A network structure that
consists of three branches and has the appearance of the
capital letter Y or T.
