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 (63607-00 ) 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 |
