Given the following voltage divider circuit, where V1 is a 9V battery, R1 is implemented using two terminals of a 10k pot so that R1 is a variable over the range 0 <= R1 <= 10kiloohlm. What is the largest value of the resistor R1 that will permit the output voltage to vary over the range that includes at least 1.5V <= V2 <= 5.0 V? Then, find a resitor (or a combinations of resistors) that are common types that would get as close as possible but not larger than the calculated value for R2.
Given the following voltage divider circuit, both resistors R1 and R2 are implemented using the three terminals of a 10k pot so that R1 and R2 are both variables such that 0<=R2 <=10kiloolhms and R1 +R2 = 10kiloolhms. V1 is a 10V battery voltage source. Find the range of values for R2 that wil cause the output voltage to vary over the range 1.5V<= V2<= 5.0V.
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…
