QTC Test Rig
This Test Rig provides a simple but elegant system for studying the new Quantum Tunnelling Composite polymer, QTC.
Resistor Kit A
An Advancing Physics pack for Sensing Unit 110E comprising 10 resistors covering the range 120Ω to 2.2MΩ , 5% tolerance
Resistor Kit B
Also for Advancing Physics Sensing Unit 110E. Five resistors coded A to E of values 300kΩ, 100kΩ, 75kΩ, 150kΩ, 100kΩ
Mini substitution unit using a single rotary switch to select from twelve values all at 5% 0.5W. Values are 100Ω,
Resistance Substitution Box
A robust resistance substitution box rated at 2W. Resistors are selected by means of 4mm sockets and can be arranged
A traditional wire potentiometer comprising 1m of 0.56mm diameter constantan wire on a hardwood base.
Connection is by 4mm
Resistance Wire Board
This apparatus provides the basis for student investigations into resistance.
Four wires, 50cm long mounted on a hardwood and acrylic
Having the same construction and size as the Resistance Wire Board 10-410, this unit provides four wires of the same
To make sliding contact with potentiometer or resistance wires. A black plastic handle carries a brass spade contact at the
Twelve non-electrolytic capacitors selected by a rotary switch mounted on an acrylic base measuring 80 × 70 × 60mm. Values
