Please show steps for solving this question. Specifically
addressing how to write the KVL equations when the current and
voltage + and - seem to contradict. For example, I think Ic should
drop voltage when going up over the resistor. Is it ok to change
the current reference direction before solving or would that throw
off the answer?

please answer every question below! many thanks!
You got a resistor (R=20 Ohm) a capacitor (C=2.0mF) and an inductor (L=20mH) you can connect in series with an ac-power supply. Sketch how R, and the reactance X_c and X_L depend on frequency f. Determine the f-region where X_c larger than R and the f-region where X_L is larger than R. What is the resonance frequency f_0 (or angular frequency omega_0) of your circuit. How could you change f_0? (put another R,...

can someone show me how to do this please
i think i was taught that when i want to find the output
resistance then all i need to do is short circuit the input voltage
and add a nominal voltage attached to Vout inorder relate with ohms
law to find output resistance
thank you

In class we solved an example circuit on the board where the resistor equaled 1000 0. We found the exact answer, and it was V = 0.7271 V and I = 4.273 mA. If we lower the resistor value so more current can flow in the circuit, what will the new exact answer be? Do you think the diode voltage will increase or decrease? Find out by solving the circuit below for I and V using the iterative method. Make...
