Analysis of two and four-lead resistance measurements Johnny Greavu University of Minnesota-Twin Cities September 29‚ 2014 Introduction We measured the resistance per foot of a wire using setups of both two and four test leads in tandem with a digital voltmeter (DVM) and compared their accuracy. While resistance can be determined by measuring voltage and current separately‚ it can also be measured more simply and directly using the resistance measuring feature available to some digital voltmeters

different granular solid; with up to 3 trials on each solid. When all tests are done and put in tables‚ and the calculations are made‚ the conclusion is that grain size does not affect that fraction of air. To be able to find the fraction of air‚ 3 measurement had to be taken‚ the volume of the solid with air‚ the volume of water‚ and the volume of the solid with water. When finding the volume of the solid with air a graduated cylinder had to be fined ⅓ of the way full‚ and measured to the tenth. Then

DEN 302 Applied Aerodynamics SURFACE PRESSURE MEASUREMENTS ON AN AEROFOIL IN TRANSONIC FLOW Abstract The objective of this exercise is to measure the pressure distribution across the surface on an aerofoil in a wind tunnel. The aerofoil is tested under several different Mach numbers from subsonic to supercritical. The purpose of measuring the pressure distributions is to assess the validity of the Prandtl-Glauert law and to discuss the changing chracteristics of the flow as the Mach number increases

Careful measurement of emf and or internal resistance of a cell Aim To measure voltage and current in the circuit and from that figure work out emf and internal resistance of the cell‚ to identify errors involved and deal with them in the most effective way and maintain a safe working environment at all times. Background EMF (electromotive force) is a measure of work done per unit of charge and is measured in volts. Internal resistance is resistance in ohms of the cell. I will be using a 1.5V battery
