1\$\begingroup\$ @soosai_steven, it's a very well-known term in circuit theory. \$\endgroup\$– The PhotonCommented Jul 9, 2016 at 15:38

Generally we define a supernode around two nodes connected by a voltage source, in order to facilitate a solution to a circuit by the modified nodal analysis.
If you connect a resistor across a voltage source, you get a current through it determined by Ohm's Law, regardless of whether we're analyzing the circuit with MNA, mesh analysis, or any other method.

If a resistor is connected across the terminals of a supernode, then the resistor terminals will remain at the voltage across the terminals of the supernode. The resistor will allow current to flow between the terminals of the supernode. The current is dependent on the value of the resistor. The current can be calculated using Ohm's Law: I = V/R

\$\begingroup\$ If I am correct, a voltage applied across a resistor will create a current that's size is dependent on the size of the resistor. Power is dependent on current and voltage. \$\endgroup\$ Commented Jul 9, 2016 at 15:00

\$\begingroup\$ that could make an improvement to your answer (edit your answer). Use the word Value rather than "size". \$\endgroup\$– MarlaCommented Jul 9, 2016 at 15:03
