In a bridge circuit , R2 =R3=100 Ω. The strain-gage resistance of zero strain is 110 Ω, and the value of R4 is adjusted to bring the bridge into balance at zero-strain conditions. The gage factor is 2. Calculate the strain for output voltage of 900 µV and power voltage of 6 V when a high-impedance detector is used.
please see attachment for problem.
See attached question #1. I got this wrong on a practice test. Can you show me how to get to the 11 k ohms ans? (See attached file for full problem description)
See attachement question is at the top of page. I got this wrong and can not seem to find the right formula. Please show me how it is done right.
Please see attached node voltage problem #3 on the bottom of the page. I got this right but I guessed. Can you show me how to solve it properly?
See attached question at the top of page. Find the thevenin equivalent circuit with respect to terminals a and b. What is the proper way to solve? Thank you.
Could you show me how to solve question 6 on the attached file? Assume that op amp is ideal.
A personal computer that has a built in monitor and keyboard requires 40W at 115V(RMS). What is the rms value of the current carried by the power cord?Can you show me how to solve this problem?
Resistor Transfer Characteristics
Write a Matlab script to plot the transfer characteristics of a resistor as shown in Fig. 1.1 (step 10) with V=1V and R=1kΩ. (Use these commands, R=1000; V=[0: 0.1:1]; I=V/R; plot(V-I)). Are these graphs are identical? (See attached file for full problem description)
Voltage across Wheatstone Bridge
Derive the formula to find the voltage across the terminals AB of a Wheatstone Bridge as shown in Fig.1.2 (see attached file) and then calculate the actual value with the components as shown. See attached file for full problem description.
