Shunt resistor equation
WebTo determine the parallel reactance, we use Equation 3, so. So XP2 = 21.21 Ω. If we wanted to, we could replace XS2, XP2, and the 2.1 Ω resistor with a single parallel resistor equal to 212.1 Ω and the circuit would present the same impedance to the source at 100 MHz. This can be simulated in LTspice. WebWith Equation 5, it is now possible to calculate the required shunt resistance for a given bridge detuning Ud / Us. For a negative effect of the shunt resistor set it parallel to R1 or parallel to R3. For a positive effect of the shunt resistor, …

WebThe gain adjust factor is derived using theoretical (simulated) signal levels that should result from engaging a shunt resistor across one leg of a bridge sensor and the measured … WebForce sensing resistors are a piezoresistive sensing technology. This means they are passive elements that function as a variable resistor in an electrical circuit. As shown in Figure 1, when unloaded, the sensor has a high resistance (on the order of Megaohms (MΩ)) that drops as force is applied (usually on the order of Kiloohms (KΩ)).
WebIn a DC shunt motor, the variable resistor is connected in series with the shunt field winding. ... The connection diagram of this method is as shown in the below figure. Fig-7. From the above circuit diagram, the equation of the shunt field current is; By increasing the value of resistance, the field current decrease and hence the flux is reduced.
