Given the following voltage divider, R1 is fixed and R2 is implemented using two terminals of a 10k pot so that R2 is a variable over the range of 0<=R2<= 10 kiloolhm. V1 is a voltage source from a 9 V battery. What is the largest value of R1 that will allow the output voltage to vary over a range that includes at least 1.5V<= V2 <= 5.0V. Then, determine a resistor (or a combination of resistors) of standard type you might that will get as close as possible to but not larger than the calculated value of R1.

- 1. Laboratory Task Descriptions Verification of series RLC transient analysis computations For this laboratory exercise, students will construct an underdamped series RLC circuit, then make voltage and current measurements to investigate the validity of transient circuit analysis techniques for series RLC circuits. Measurements will be obtained using the oscilloscopes available in the laboratory. The signal generator will be used to apply a 0[V] to 10[V], 50[%] duty cycle square wave across the RLC circuit to establish the circuit response. The required square wave signal frequency for the RLC circuit will be computed below in part 2b of the prelab work. Note: To receive credit for the following prelab computations, all required equations for the prelab below must be generated in variable form before substituting component values. Generation of the equations in variable form is required to permit substituting the actual measured component values into the solution equations. This…arrow_forward1.
