The direction of current is determined by the voltage source that is controlling it. If the voltage source is in series with the current, the current will flow in the same direction as the voltage. If the voltage source is in parallel with the current, the current will flow in the opposite direction of the voltage.
Dependent current sources can be handled by using the controlling variable (e.g. voltage or current) in the mesh equations. The controlling variable should be expressed in terms of the unknown mesh currents and substituted into the equations.
A voltage controlled voltage source is controlled by a voltage in the circuit, while a current controlled voltage source is controlled by a current in the circuit. In mesh analysis, voltage controlled voltage sources are treated as independent voltage sources, while current controlled voltage sources are treated as dependent current sources.
Yes, mesh analysis can be used with non-linear circuits. However, the equations will be more complex and may require iteration to find a solution.
Mesh analysis is best suited for circuits with multiple current sources and voltage sources, as it allows for solving multiple equations simultaneously. It may also be a better choice for circuits with complex or non-linear elements, as it can provide more accurate results compared to other methods.
