Computer analysis of the circuit shown in the Figure indicates that the values of the node voltages are v1=20 angle (-90 deg) and V2=44.7 angle (-63.4deg).

Computer analysis of the circuit shown in the Figure indicates that the values of the node voltages are v1=20 angle (-90 deg) and V2=44.7 angle (-63.4deg). Are these values correct? Hint: Calculate the current in each element using the values of V1 and V2. Check to see if KCL is satisfied at each node of the circuit. Work out the solution so we know that KCL is satisfied.

The circuit shown in the Figure was built in the lab and v0 was measured to be 6.25V.

The circuit shown in the Figure was built in the lab and v0 was measured to be 6.25V. Verify this measurement using the voltage divider principle. See attached pdf file for Figure.

Conservation of energy requires that the sum of the power absorbed by all the elements in a circuit be zero. The following Figure shows a circuit.

Conservation of energy requires that the sum of the power absorbed by all the elements in a circuit be zero. The following Figure shows a circuit. All of the element voltage and current are specified. Are these voltages and currents correct? Hint: Calculate the power absorbed by each element and add them up. Work out the solutions so we know how you arrived at your answer.
