Computing nodal voltages and voltage source currents.

Takes input as netlist format:
Component_Type | Node1 | Node2 | Value | Initial_Value

• Component_Type stands for the type of the component. It can be one of the following:
  ⋅⋅* Voltage Source "Vsrc".
  ⋅⋅* Current Source "Isrc".
  ⋅⋅* Resistance "R".
  ⋅⋅* Inductor "I".
  ⋅⋅* Capacitor "C".

* Node1 and Node2 stands for the nodes‟ numbers to which the component is connected to. * Value is the physical value of the component. * Initial_Value is the initial current or voltage that is observed on the component at time=0.
##### Sample input (no transient):
Vsrc 1 0 4 0 Vsrc 3 2 6 0 R 1 2 1 0 R 2 0 4 0 R 3 0 2 0 Isrc 1 2 1 0

Sample output:

The circuit Graph representation (node,value): node0 node1 -> (0,4.00) -> (2,1.00) -> (2,1.00) node2 -> (0,4.00) node3 -> (2,6.00) -> (0,2.00)
t | V1 | V2 | V3 | I1 | I2 0.0 | 4.000000 | -0.000000 | 6.000000 | -3.000000 | -3.000000

Sample input (with transient):

R 1 0 1 0 C 1 0 1 0 R 1 2 1 0 I 2 0 1 0 Isrc 2 0 1 0
##### Sample output:
The circuit Graph representation (node,value): node0 node1 -> (0,1.00) -> (0,1.00) -> (2,1.00) node2 -> (0,1.00) -> (0,1.00)
