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.
