Question

In a Wien-bridge oscillator circuit, there are four resistors, two capacitors, and an op amp. Each resistor have a tolerance of 5%. the resistor R = 5950 ohms, R1 = 3 ohms, Rf = 6.05 ohms, capacitor = 1uF. Compute Vo and R at a frequency of 300Hz, 500Hz, 800Hz, and 1000Hz.

Answer #1

Two resistors, each with a resistance of 200 MΩ are connected
in parallel. Two capacitors, each with a capacitance of 10 μF are
connected in series. The combination of resistors and the
combination of capacitors are then connected in series with a
battery supplying an emf of 12 V. The electrical circuit is
completed. The capacitors are uncharged at the beginning.
(a) Illustrate the circuit.
(b) Calculate the capacitive time constant of the circuit.
(c) What fraction of the final...

Consider the circuit shown in the figure(Figure 1). Suppose the
four resistors in this circuit have the values R1 = 13 Ω , R2 = 7.2
Ω , R3 = 6.9 Ω , and R4 = 11 Ω , and that the emf of the battery is
E = 15 V . You may want to review (Pages 748 - 751) . Find the
current through each resistor using the rules for series and
parallel resistors. Express your answers using...

Part 1: I need to design a circuit using only resistors and
capacitors that will filter out a signal above a specific
frequency. In order to be deemed a success, the peak voltage across
your capacitor must be equal to 20% of the peak voltage provided by
the function generator at the frequency f_theory. Full credit on
this lab requires that your percent error in Part 2 is less than
5%. f theory = 1699Hz
Available values of resistance are...

Assume you are given two resistors with resistances R1=4.0 kΩ
and R2=6.0 kΩ and two capacitors with capacitances C1=4.0 µF and
C2=6.0 µF.
a) Calculate the equivalent resistances Req and the equivalent
capacitance Ceq if the resistors are connected in series and the
capacitors are connected in parallel.
b) Now, use the Req and Ceq that you calculate in part (a) to
construct an RC circuit. If an emf of 27 V is suddenly applied
across Req and Ceq, calculate...
