Resistance Apparatus
EM-8812
® 3
Introduction
In the Resistance Apparatus, a current is established in a wire of known diameter, and the voltage drop across a
section of the wire is measured. Students can calculate the resistance of the wire and the resistivity of the material.
Included Equipment Part Number
Resistance Apparatus EM-8812
Two sets of wire (8 wires per set) in storage tube EM-8813
Fuses (one installed and one spare), 2 A mini-blade 530-045
Other Equipment Recommended
Voltage measurement:
Galvanometer Sensor
1
1 Sensor requires a PASPORT interface such as Xplorer GLX (PS-2002).
PS-2160
or Multimeter SE-9786A or similar
Current measurement:
Galvanometer Sensor
1, 2
2 Two Galvanometer sensors can be used simultaneously to measure voltage and current. Second sensor
requires a multi-port interface or two single-port interfaces.
PS-2160
or Multimeter SE-9786A or similar
or current meter of power supply
Power Supply (capable of at least 1 A) PI-9877 or SE-9720A
Patch Cords (4mm banana plug) SE-7123
