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

CASCADE CONNECTION A series connection of amplifier stages‚ networks‚ or tuning circuits in which the output of one feeds the input of the next. Also known as tandem connection. Fig. 16. Two two-port networks with the first’s output port connected to the second’s input port When two-ports are connected with the output port of the first connected to the input port of the second (a cascade connection) as shown in figure 16‚ the best choice of two-port parameter is the ABCD-parameters.

Introduction An operation amplifier (op-amp) is an integrated circuit that amplifies the differential voltage between non-inverting input and inverting input to yield a single amplified output. In An operational amplifier (op-amp) is an integrated circuit that amplifiers the difference between two inputs voltages and produces a single output. The op-amp is prevalent in analogue electronics‚ and can be thought of another electronics device which is bipolar or field-effect transistor. The op-amp
