Lab# 1 The Node-Voltage Method of Circuit Analysis By: Abstract This report used KCL and Ohm’s law to calculate the node voltages and compare them to the measured node voltages after building the circuit. The calculations were obtained by hand using node analysis. The experiment was simulated on PSpice and the results were verified to hand calculations. The circuit was built in the lab and the results were measured with a digital multi-meter and compared to the calculated values‚ and

In metals it would be called an alloy. 2. An aqueous solution of KCl is colorless‚ KMnO4 is purple‚ and K2Cr2O7 is orange. What color would you expect of an aqueous solution of Na2Cr2O7? Explain. Orange. 3. Explain why hexane will dissolve benzene but will not dissolve sodium chloride. Sodium chloride is an ionic
