For the circuits shown in Fig. 2, use the mesh-current method to calculate the indicated mesh currents. In lab, build each circuit and use the multimeter to measure all of the resistor currents. (Use the ammeter or use the voltmeter + Ohm’s Law). Show that the measured resistor currents are consistent with the calculated mesh currents.
source transformations, node voltage, mesh current, superposition) find the required complex voltages and currents in the current. 4. Grind through the complex algebra to find the required voltages and currents. 5. When finished, express the complex voltages and currents in magnitude and phase form.

2020年12月21日 · Fundamentals — voltage, current, energy, power; Basic circuit analysis techniques. Most useful are: equivalent resistances (impedances), voltage and current dividers, and node-voltage analysis. Source transformations and superposition can be used at times. Mesh analysis is occasionally useful. Basic calculus — derivatives and integrals
