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

Unit 4222-335 Undertake physiological measurements 1.1 We should always check equipment which we are going to use if it is safe and working properly‚ we should wear PPE every time we are undertaking any task‚ ensure that we are trained to do the task‚ we should keep the working place safe and clean. When we are about to take measurement from an person we need to make sure that the person know exactly what we are going to do and asking permission for the task we are about to do. Recording the task

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

EKG Measurement and Interpretation at Rest and During Exercise Jonathan Murdock March 5‚ 2013 March 19‚ 2013 (KIN 375) Purpose: In the United States‚ people suffer from heart problems every day. According to the Centers of Disease Control and Prevention (CDC)‚ every year about 935‚000 people in the United States suffer from a heart attack and about 600‚000 die from heart problems. Electrocardiograms (EKG or ECG) provide important information concerning the electrical activity

Techniques and Measurements Course Number: CHE 111 Abstract: This experiment introduced the student to lab techniques and measurements. It started with measuring length. An example of this would be the length of a nickel‚ which is 2cm. The next part of the experiment was measuring temperature. I found that water boils around 95ºC at 6600ft. Ice also has a significant effect on the temperature of water from the tap. Ice dropped the temperature about 15ºC. Volumetric measurements were the basis

exchange rates for the pound‚ yen and euro with their nominal exchanges rates. What differences do you observe? What accounts for those differences? PPP exchange rates are the converted currency rates that equalize the purchasing power of different currencies for a given basket of goods by eliminating the differences in price levels between countries. The following is the comparison of the PPP exchange rates for pound‚ yen and euro between their nominal exchange rates in 2009‚ shows that PPP exchange

(OCT) were recorded. The patients received an explanation of the Visual Analog Scale (VAS) (Figure 1) prior to the injection and were asked immediately (within 2 minutes) after IVB injection to rate their perceived pain during the injection on a VAS of 0 (no pain) to 10 (unbearable/worst pain). The average of pain scores was considered as the primary outcome measure. BCVA and CMT measurement was repeated one month after injection.[37] Preparation and administration of IVB was performed as recommended
