Kanthal ® a-1 is a ferritic iron-chromium-aluminium alloy (fecral alloy) for use at temperatures up to 1400°c (2550°f) the alloy is characterized by high resistivity and very good oxidation resistance. Direct-current circuits 71 introduction electrical circuits connect power supplies to loads such as resistors, motors, heaters, or lamps the connection between the supply and the load is made by soldering with wires. Theoretical analysis on ac resistance of copper clad aluminum wires kenichiro yashiro, 1 2chihiro kamidaki, 4takashi shinmoto,3 and ning guan wireless power transfer system using inductive coupling through magnetic field requires low wire model for analysis.
This is shown because when the length of wire was 40cm long (28 gauge) the resistance average was 2 9 ohms, at 100cm the resistance average was 5 4 ohms and finally at 160cm the resistance average was 7 9 ohms. Extended experimental investigation: electricity • systematic analysis of primary and secondary data to identify relationships between patterns, trends, errors and from the measurement of the total resistance to give the resistance of the copper wire that was to be measured. Graph, the lower the resistance of the wire the connection between current, voltage and resistance was discovered in 1827 by georg ohm, a german physics and maths teacher the formula v = i × r is known as ohm’s law it was such an important discovery that the unit of resistance is called the ohm it is represented by the symbol w.
