Product Information
An excellent apparatus for showing how resistance varies with the type of wire, length of wire, and diameter of wire in coils. The apparatus can be used with a Wheatstone Bridge or ohmmeter. Wire lengths are in two to one ratios to simplify computations. Five coils are mounted on a wooden block and six binding posts facilitate hook-up.
The coils are wound as follows:
Copper Nickel Wire AWG 22 Length 10 meters
Copper Wire AWG 22 Length 10 meters
Copper Wire AWG 28 Length 10 meters
Copper Wire AWG 22 Length 20 meters
Copper Wire AWG 28 Length 20 meters
