Record voltage, current and diameter of the wire, d (supplied by the manufacture). Calculate resistance and cross section area, A, in mm 2 (A = \(\frac{{\Pi d}^2}{4}\)). Plot a graph of resistance ...

Record voltage, current and diameter of the wire, d (supplied by the manufacture). Calculate resistance and cross section area, A, in mm 2 (A = \(\frac {{\pi }d^2}{4}\)). Plot a graph of ...

One of the most basic concepts of technical analysis is support and resistance. Key points below the current price are known as support, and those above the current price are resistance.
