Utilizing a Strain Gage Circuit to Measure Weight as Function of Changing Resistance John C. Greavu III University of Minnesota‚ School of Physics and Astronomy I. INTRODUCTION Operational amplifiers can be combined with gages to accurately measure mechanical properties as functions of electrical variables of a circuit. Here‚ we used two strain gages on the inside and outside of a load cell to measure the mass of hanging weights as a function of voltage. As the resistance of a wire is proportional

Purpose: The purpose of this experiment is to study the basics of a direct current circuit. There are several parts to this experiment‚ where resistors are set up as parallel‚ series or both. We measure the potential difference and current measured by voltmeter and ammeter respectively. Also‚ we set up a Wheatson Bridge to measure the unknown resistor. Equipment: Voltmeter PCC 000218 Galvanometer PCC 000180

in the bulb vibrated fast and the bulb became warmer as the resistance increased. As the voltage increased the current and resistance did also. The resistance of the 6V bulb increased as the current and voltage did. However‚ in the pure resistor trial experiment the resistance stayed around the same as the current and voltage increased. The difference between the bulbs and trial experiment graphs are that the bulb graph was a straight line with an increasingly deeper gradient and

Objective In experiment 2 our main objective was to understand the analysis of resistors‚ inductors and capacitors in a sine wave circuit. we measured the impedance of the inductor and capacitor using a current sensing resistor. Inductive reactance is the opposition to the flow of current‚ and capacitive reactance is the opposition to the flow of charge. The tools we used for this experiment a pair of resistors‚ an inductor‚ a capacitor‚ dual channel oscilloscope‚ audio oscillator‚ and a digital
