PHYS222 Prelab High Pass-Low Pass Filters See sections 31.6 through 31.10 of Halliday, Resnick and Walker 7th ed. 1. What is the objective of this experiment? 2. For a sinusoidally applied voltage, the current in a capacitor always______________ the voltage by __________degrees. Explain this statement. 3. What is reactive capacitance? (Give equation and explanation). 4. Given a resistor with a value of 10k ohm and a capacitance of 10 nanofarads, find the capacitive reactance at 1600 hz. Include units. 5. What is a high pass filter? (see lab introduction on “crossover network”) 6. What is a low pass filter? (see lab introduction on “crossover network”) 7. For RC circuits, the frequency at which the magnitudes of the impedances of both components (i.e., Xc and R) are equal is called the break point or cut off frequency, fb. Thus fb = 1/(2πRC. What is the break point frequency of the values of R and C given in question 4 above?
