Question

write down equations for all node voltages of the circuit​

Answer 1

Answer:

The Node Voltage Method breaks down circuit analysis into this sequence of steps,

->Assign a reference node (ground).

->Assign node voltage names to the remaining nodes.

->Solve the easy nodes first, the ones with a voltage source connected to the reference node.

->Write Kirchhoff's Current Law for each node. Do Ohm's Law in your head.

->Solve the resulting system of equations for all node voltages.

->Solve for any currents you want to know using Ohm's Law.
