    Actually I'm just curious to know when and where we can apply mesh and nodal analyses. Perhaps, you can help me to understand this with some simple circuit diagrams. Thanks

    1: To apply nodal analysis we must have at least two nodes. Am I correct? Moreover, we also need one extra node which would be used as a reference node - so in total we need three nodes.

    2: To apply mesh analysis we must have at least two meshes. In mesh analysis we need to subtract the current of loop from the current of the other. So, if we have a single loop, then we have only one current, therefore having at least two meshes is a must.

    Please help me.
