VIN PROBLEM-H The Input of the first op-amp is not given. So, they can't ask us to calculate the Output of the Circuit. So, we can only calculate the Voltage Gain A,= in Number not in Volts. + 5KQ VIN Vout nus 20k wwww 10K S2 VouT The Negative Feedback Resistance of the 2 OP-AMP is OSL.
Use NV, MC, and Superposition methods, each one at a time to determine L in the circuit shown below. Show all work in as much detail as possible. Redraw the circuit and examine if current is balanced at each node.
3) a) Write a report describing the significance of strain gauges and Wheatstone bridge in applications from a chosen area of mechanical or civil or electrical/robotics engineering. Your report should contain a genuine literature review (not a website from a Google search; with a minimum of 2-3 references), diagrams and structured into: title, introduction, main body, references and appendices. The report should not exceed 500 words excluding appendices and should be written in your own words. b) Below is the arrangement of strain gauges in the Wheatstone bridge. Solve V using a voltage nodal analysis for a given Vdc-10V. Show that V=0 when R1=R2=R3=R4=R (say). Find out the value of V for a given R1=R4=10 ohms and R2=R3= 20 ohms.
Question Use the principle of superposition to determine in the circuit shown below. Redraw the circult and examine if current is balanced at each node.
Q 1 Given the values: R₁ = 214 R₂ = 364 C = 286 μF w = 12 By how much is the phase angle of the output voltage signal shifted Q 2 Given the values: R₁ = 225 R₂ = 386 C=271 μF w = 8 Calculate the amplitude of voltage gain. compared to the phase of the input voltage signal? Q 3 For the values R₁ = 981 , R₂ = 430 , C = 293 μF, w = 8; calculate b₂ ratio Hint: This form of G, is just another way of writing ZL ZL + ZT So just ZL start with the formula we know from class (Z₁ + ZT -), and you will find yourself arriving at the form of G, mentioned above in the question. And then it would be easy to get the ratio.
a) What is the current flowing through R2? b) If the value of resistor R3 in the circuit is reduced by half, does the current through resistor R1 increase or decrease?
Use Thevenin's Theorem to find I. Also, draw the Norton circuit. V w w 4 ΚΩ 2 ΚΩ 20 V 32 ΚΩ + 2V
