The Potential Divider shown below has a load resistor of 50 Ohms attached (across VOUT). What is the voltage measured across VOUT? NB You will have to first calculate a new value of resistance for R2 and the load resistor in parallel. VIN is 15V, R1 = 4.780hms and R2 = 84.40hms. R1 VOUT VN -O R2 Answer:For the OpAmp wired as shown in the diagram, the 1k resistor is replaced with a 1.138 k resistor. The function generator is supplying a 7V peak sine wave. Assuming the power supply to the Op Amp is plus/ minus 40V, what is the peak output voltage in volts? Hint: careful with polarity of output. Answer: For a standard Op Amp as shown in the diagram with a very high voltage gain of 0.1M, the 7microvolt supply is replaced with a 3.528 microvolt supply. Assuming the power supply to the Op Amp is plus/ minus 20V, what is the output voltage in volts? Answer: What is the total impedance in M Ohms, of a series RLC circuit, if R= 1.0 kQ, XL = 3936891.6 0, and Xc =4.78 MO? Answer:Find the feedback resistance in kOhm required for a non-inverting amplifier which is to have a voltage gain of 70 and an input resistance of 5K0
