Abstract

The invention discloses a method for giving an output resistance value of a series and parallel combination, and aims to provide a method, which is rapid in giving and high in accuracy and is accurate, for giving the output resistance value of the series and parallel combination. The method is implemented according to the following technical schemes of taking 100 ohm as an interval value, and employing and connecting four 200-ohm resistance units and a 100-ohm resistance unit in series to form a hundred-resistance combination body having arithmetic progression resistance and having access circuit range being 0-900 ohms; taking 10 ohm as an interval value, and connecting in series to form a decade-resistance combination body with access circuit range being 0-90 ohms according to the mode; taking 1 ohm as an interval value, and connecting in series to form a unit-resistance combination body with access circuit range being 0-9 ohms according to the mode; and taking 0.1 ohm as an intervalvalue, and connecting in series to form a decile-resistance combination body with access circuit range being 0-0.9 ohms according to the mode so that the maximum value is 900+90+9+0.9=999.9 ohms, wherein the minimum resolution is given by a 0.1-ohm resistor.

Description

technical field [0001] The invention is mainly used to provide a method for providing a test environment of resistance signals in series-parallel combination to give an output resistance value. Background technique [0002] Resistors, capacitors, and inductors are the most commonly used components and types in electronic circuits. Resistors are divided into fixed resistors and variable resistors. Adjustable resistance is a kind of resistance, it can play the role of resistance in electronic circuits, it is different from general resistance in that its resistance value can be continuously changed within a certain range, and in some cases where the resistance value is required to change but not often In case of change, an adjustable resistor can be used. Due to the structure and use of adjustable resistors, the failure rate is significantly higher than that of ordinary resistors. There are many kinds of adjustable resistors with different structures and different definition...
