Replacement Wires, Resistivity ApparatusReplacement set of wires for the Resistivity Apparatus (EM-8812).
Resistance Selector
Resistance SelectorMini substitution unit using a single rotary switch to select from twelve values all at 5% 0.5W.
Resistance Substitution Box
Resistance Substitution BoxA robust Resistance Substitution Box rated at 2W. Resistors are selected by means of 4mm sockets and can be arranged in series to give the full range from 1 to 12,221Ω.
Resistance Wire Board
Resistance Wire BoardThe Resistivity Board provides four wires of the same diameter but different materials.
Resistivity Apparatus
Resistivity ApparatusStudents can calculate the resistance of the wire and the resistivity of the material.
Resistivity Experiment
Resistivity ExperimentDiscover the relationship between the resistance of a wire and its length, diameter, and the resistivity of the metal.
Resistor holder
Resistor holderUp to four resistors (or other components) can be mounted in terminal blocks, which are individually connected to safety terminals. Used when unmounted components are to be included in a circuit with conventional safety cables.
Resistor Kit A
Resistor Kit APacks of 10 resistors covering the range 120Ω to 2.2MΩ, 5% tolerance together with 100 resistors 22kΩ on a bandolier.
Resistor Kit B
Resistor Kit BAlso for Advancing Physics Sensing Unit 110E. Five colour-sleeved resistors of values 300kΩ, 100kΩ, 75kΩ, 150kΩ and 100kΩ all at 5% tolerance.
Resistor Pack
Resistor PackAssortment of electrical resistors ranging from 10 ohms to 330 kilohms.
Resistors on base, 20, 50, 100, 150 Ohm
Resistors on base, 20, 50, 100, 150 OhmFour precision resistors mounted with safety bushings. The resistors can be combined in series and parallel connection with ordinary safety wires in countless ways.
Resolved Forces Board
Resolved Forces BoardBy using spring balances on an easy to understand layout the concept of balanced and resolved forces is easy to demonstrate. The attachment points can be put in line for collinear forces where the single force is the sum of the other two. For 2D work, angles and vectors can be easily examined. The durable white plastic-coated board measures 800 x 450mm and comes complete with balances and full instructions.
Resonance Air Column
Resonance Air ColumnResonance tube with plunger, node markers and detachable stands for performing waves and sound experiments.

Ripple Tank MkIII
Ripple Tank MkIIIThis compact unit provides an elegant method of demonstrating the wave phenomena of reflection, diffraction, refraction and interference with none of the setting-up problems usually associated with ripple tanks. The concept has been further developed to offer new features and simplicity in this MkIII design.
