Chapter 03.03 Bisection Method of Solving a Nonlinear Equation – More Examples Electrical Engineering Example 1 Thermistors are temperature-measuring devices based on the principle that the thermistor material exhibits a change in electrical resistance with a change in temperature. By measuring the resistance of the thermistor material, one can then determine the temperature. For a 10K3A Betatherm thermistor, Figure 1 A typical thermistor. Thermally conductive epoxy coating Tin plated copper alloy lead wires the relationship between the resistance R of the thermistor and the temperature is given by   3 8 4 3 ln 10 775468 . 8 ) ln( 10 341077 . 2 10 129241 . 1 1 R R T where T is in Kelvin and R is in ohms. A thermistor error of no more than C 01 . 0 is acceptable. To find the range of the resistance that is within this acceptable limit at , we need to solve C 19   3 8 4 3 ln 10 775468 . 8 ) ln( 10 341077 . 2 10 129241 . 1 15 . 273 01 . 19 1 R R and   3 8 4 3 ln 10 775468 . 8 ) ln( 10 341077 . 2 10 129241 . 1 15 . 273 99 . 18 1 R R 03.03.1

03.03.2 Chapter 03.03 Use the bisection method of finding roots of equations to find the resistance R at . Conduct three iterations to estimate the root of the above equation. Find the absolute relative approximate error at the end of each iteration and the number of significant digits at least correct at the end of each iteration. C
