Find using superposition rule: Solution Superposition The superposition theorem states that the response (voltage or current) in any branch of a linear circuit which has more than one independent source equals the algebraic sum of the responses caused by each independent source acting alone, while all other independent sources are turned off (made zero).
A three-node circuit is solved by using the voltage of voltage sources. The nodal analysis is not used since there are enough voltage sources to determine all node voltages.
Solve the circuit by nodal analysis and find the power of . Solution a) Choose a reference node, label node voltages:
A circuit with four nodes is solved by the nodal analysis. The circuit has three current circuits and three resistors.
