Suggest values for R₁ and R₂ to sustain oscillation. Explain why the gain must be set as such. R₁ R 20 M c R R2 R Vo

3) Load for a circuit with direct current source voltage The waveform of the voltage generated on it is below shown. Source for this working circuit that is symmetrical The value of the voltage and load resistance is 100 V and 5Ω respectively.It is given as. Find what is required below. a) Draw, indicating the name of the circuit to be used. b) Draw the door signs c) Find the effective value of the output voltage at the main frequency.

Impedances. In alternating current, the resonance frequency is defined as the frequency that would make the effect of the reactive elements eliminate each other in a circuit, so that the effect of the impedance would be purely resistive, and the maximum active power. Knowing the above, calculate the resonance frequency of the following circuit, then with that frequency calculate the equivalent impedance seen by the source and verify that the circuit is purely resistive. 20 N 2 H VF N 100 μF 100 kn 4Ω.
