Post Office Box Trainer

Description: Post Office Box Trainer - Sample : Constantan, Nichrome. Provided with DC power supply. Post Office Box Trainer is the combination of resistances which work on the principle of Wheatstone Bridge. Post Office Box is helpful to determine the unknown resistance of wires like Constantan, and Nichrome etc. With the help of NV6041 we can determine the specific resistance of different types of wire. Post Office Box can also verify the combination of resistances in series and parallel. Sample : Constantan, Nichrome Provided with DC power supply Compact design Easy to operate Determination of unknown resistance. Determination of resistivity of the material of wire. Verification of effects of resistances in series and parallel.
