WebThis experiment can be used to teach about the idea of validity of scientific results. Results may be rendered invalid if an uncontrolled factor affects the results. In this case, the temperature of the wire is a factor which affects measurements of its resistance. Discuss how this can be taken account of. WebPredicts that the longer the wire the more resistance it will have as there are more atoms for the electrons to hit. Explains that thin wire is created by rolling out a thicker peace there is less space between atoms for the electrons to flow through. Describes the method of measuring voltage and current for 100 centimetres of 30 swg resistance ...

WebJan 12, 2024 · Mr Habgood shows you how to measure the resistance of a wire when you change its length. WebWe performed a ultra-short width high voltage pulse electrolysis using a thin Pd wire cathode; a diluted electrolytic solution of D2O+LiOD was used in a peculiar wire-turned electrodes geometry. The deuterated Pd loading was evaluated by the D/Pd mahoney towing

WebApr 12, 2024 · Resistivity inversion plays a significant role in recent geological exploration, which can obtain formation information through logging data. However, resistivity inversion faces various challenges in practice. Conventional inversion approaches are always time-consuming, nonlinear, non-uniqueness, and ill-posed, which can result in an inaccurate … WebApr 22, 2024 · Results can be plotted on a graph.
