The stress sensor (1) has four resistors (R1-R4) that are integrated in an active surface (3) of a semiconductor chip (2), to form a Wheatstone bridge. The resistors (R3,R4) connected in series, are connected in parallel with resistors (R1,R2) that are connected in series. The ...
In the network shown you are given that \(V=V\)V and that theresistors have the resistances \(R_1 = R1 \Omega\),\(R_2 = R2 \Omega\), \(R_3 = R3 \Omega\), and \(R_4 = $R4 \Omega\).___相关知识点: 试题来源: 解析 $R3R4S 反馈 ...
The resistors pull down the microcontroller input pins when the relay contacts are open. R is chosen for the type of relay contacts specified by the designer, considering the contact material and load current. The subroutine DB_Check_Port (Listing 3) functions as follows. Figure 6. Mini...
Designing the differential amplifier by inspection is part of the art in the analog design. Inspecting the circuit and knowing how it works, it really gives you a feeling on what the values of the resistors should be. Looking back at the example I took inMasteringElectronicsDesign.com: Solving...
Resistors are R1 and R5 (10K, 1/4w); R2, R3, and R4 (37.4K, 1/4w); R7 (1K); and R8 (220 ohm 1/2w). The combination of R1, R2, D1, IC1D, R3, and C1 provides a feedback control circuit that adjusts the gain and therefore the base drive to phototransistor 26 to make...
The resistors R1 and R2 are an attenuator for V1, so that V can be determined as in the following relation. (4) By replacing V in equation (3), Vout1 becomes: (5) Now that we have Vout1 and Vout2, and using the Superposition Theorem, Vout is the algebraic sum of Vout1 and Vou...
The formula for calculating series resistance is:R = R1 + R2 + R3 + R4 + Rn Rn is for extrapolation. If you have more than 4 resistors, just keep adding them up by changing Rn to R4, R5, etc. You might enjoy ourresistor tutorialas well. We also have anLED resistor calculator, a...
Ideally, the resistors in differential amplifier circuits should be selected in such a way that their ratios are identical (R2/R1 = R4/R3). Any deviation from these ratios will lead to an undesired common-mode error. The ability of a differential amplifier to reject this common-mode ...
What is the equivalent resistance in a parallel of four resistors with the resistances: R1 = 5 ohms, R2 = 3.45 ohms, R3 = 6.65 ohms, and R4 = 9.88 ohms? a) 1.35 ohms b) 1.48 ohms c) 16.75 ohms d) 4.45 ohms A 4.0 ohms resistor, a 5.0 o...
The worst case equations for the resistors R1 and R2 in Figure 2 are: The first two equations ensure that the input voltage VI(430) at the input of the MSP430 MCU is above (when VI(sys) is high) or below (when VI(sys) is low) the worst case input threshold voltages. The third ...
