Nodal Analysis Step-Through

How to Use

  • Press Next Step to walk through the nodal analysis procedure
  • Each step highlights the active node and shows the KCL equation being applied
  • The final steps display the solved node voltages and all branch currents

What to Observe

  • Node identification: one node is the reference (ground); remaining nodes get voltage variables
  • KCL at each node: sum of currents leaving equals zero — currents expressed as (V_node − V_neighbor)/R
  • Matrix form: the KCL equations form a symmetric conductance matrix
  • Verification: branch currents confirm that KCL holds at every node
