resistance Finance Definition
In technical analysis, a price point or points that a futures contract or other financial instrument will have difficulty rising above. Resistance is a price level where selling pressure overcomes buying pressure and a price advance is turned back. The opposite is support, which is a technical analysis term. It indicates a price point that prices will have difficulty moving below. Technical analysts look at resistance in order to determine the market’s next likely move. For instance, if gold prices have been attempting to move higher but each day’s gain stops at $335 per ounce of gold or $336, then those two price points are where resistance occurs.
resistance (R) Telecom Definition
A measure of the opposition by a circuit, component, material, or free space to the flow of an electric current. Resistance is the value of R in the Ohm's Law equation I = V/R, where I is the electric current, and V is voltage, or the difference in electric potential between two points in a circuit. Resistance is the real part of impedance. The SI unit of measurement of resistance is the Ohm ( ).The reciprocal of resistance is conductance, the official measurement of which is the mho, which is Ohm spelled backwards. In an electrical circuit, resistance results in attenuation, or loss of signal strength. See also conductance, current, Ohm, and voltage.
