Solve the circuit and find the power of sources: , , , , , . Solution: There are three meshes in the circuit. So, we need to assign three mesh currents. It is better to have all the mesh currents loop in the same direction (usually clockwise) to prevent errors when writing out the equations.
Nodal analysis method is deployed to solve a four-node circuit which has a dependent current source. The target is to find the power of the controlled current source.
Determining power of independent voltage and current sources. Passive sign and active sign conventions are used to find out which source is supplyingpower and which one is absorbing.
Solving the circuit using nodal analysis and finding the power of the current source.
Determine the resistance of the resistor, and .
Finding power and conductance of resistors from the current and resistance
Finding the power of elements and determining which one is supplying power and which one is absorbing it.
