Kirchhoff

PHY 201 & 231

Based on Loyd #34. In this experiment, the students will construct and measure the voltage and current of multiloop circuits with multiple resistors and sources of emf. This will demonstrate the type of circuit to which Kirchoff's rules must be applied. The students will apply Kirchoff's rules to several circuits and solve for the expected currents in the circuit. They will then compare their measured experimental values of the currents in the multiloop circuits with the theoretical values predicted by Kirchoff's rules.

Equipment

Notes

Remember to put out 5 red and 5 black patch cords per table.

Put out the Extech power supplies. If there are not enough, use the Sargent-Welch power supplies. DC Circuits 3/Kirchoff 2 and Resistivity for Finch: Set up for one of the light bulbs from the “ohm’s law” law in PHY100. Just needs that bulb, wires, 2 alligator clips and power supplies. Also needs the spooled coils of wire for the usual resistivity lab.
