By replacing mechanical angle and position displacement to resistance value change of potentiometer as input and convert to DC signals in proportion to displacement by insulation.
From the characteristics shown in Fig. 4, when considering capacitors and coils as resistances, the resistance value(impedance) must be considered as a function of time(phase).
To calculate a specific temperature, you must first identify the two closest resistance values(those above and below the measured RTD value), and then interpolate between them.
By controlling the direction of spin, it changes the resistance value of the device, and matches the size of the resistance value to the digital signals“0” and“1.”.
許容損失PD=V*V/Rですので、使用環境での入力抵抗値Rinがわかれば、決定することができます。
Since the allowable loss PD V* V/R, if the input resistance value Rin in the operational environment is known, it can be determined.
CTQ', which stands for'Critical To Quality', is the most important factor that affects the quality of products on each line, for example: length, weight, resistance value etc.
Voltage divider top resistor value The voltage-divider top resistors, R1 and R5, need to be high enough so that the divider current is less than the minimum desired current value at MODSET or APCSET.
Introduction The Wheatstone bridge was developed in the early days of electronics as a way to accurately measure the value of resistors without needing an accurate voltage reference or a high-impedance meter.
One matter requiring attention is that R1 must be able to withstand high voltages(85 to 264 VAC×√2) and the power equal to the resistance value times the current.
In simpler terms, the output voltage calculated by using the resistor value and nominal value of the FB pin voltage, except for coincidence, never matches the calculated value as long as there is an allowable difference between the resistor and FB pin voltage.
For example, the description of resistor value and equations for the determination of an output voltage does not provide a great deal of details so that, basically, such items can be determined based on equations. The reason may be that it is not crucial to know the"why.
Here examples of each are given.・ Case in which variations can be directly described for symbols In this example, a simulation is performed of the resistance value(voltage/current) when a voltage is applied to a 100 Ω resistor.
A high resistance value is maintained and almost no electric current passes until the voltage reaches a certain value(varistor voltage). When the voltage exceeds thevalue, the resistance value suddenly drops and a large electric current is allowed to pass.
