please solve them ,,,, thank you so much

Extracted text: 4.7 Questions: Is there any Voltage Law' for nodes? If so, what is it? Is there any 'Current Law' for meshes? If so, what is it? Components currents references are given in the figure, any change of these current references will not affect the resulting current values, why? After the determination of the currents references, can we connect the ammeter terminals in any way in order to measure the current of a component? Can we select components voltage references randomly in order to write KVL? Why? In what situation we cannot select both current and voltage references randomly? Why? Why independent KVL and KCL equations used? What happens if dependent equations are used? Analyze the experiment circuits and calculate elements powers and energies. 1. 2. 3. 4. 5. 6. 7. 8.
