Answer the following questions:

1. How does the author call the mathematical value which includes in itself effective value and the angular frequency?

2. How a capacitor looks like in a circuit with the source at low angular frequency?

3. How a capacitor looks like in a circuit with the source at high angular frequency?

4. What is the phase shift or voltage phasor in a circuit with capacitor?

5. According to the watched videos, how does the author calls the resistance which appears in circuit with capacitor or inductor?

6. How the author of the video calls the property of current and voltage to change its direction and effective value synchronously?

7. How the author of the video calls the property of current and voltage to change its direction and the effective value asynchronously?

8. How the voltage in a circuit with capacitor behaves towards the current according to the video?

Answers:

1. The author calls them “Phasor”.

2. The capacitor in a circuit with the source at low angular frequency is presented as a break.

3. The capacitor in a circuit with the source at high angular frequency presented as a short.

4. The phase shift show as a voltage across the capacitor lags in phase behind the current. It’s equal pi/2.

5. The author calls it the reactance or reactive resistance

6. He calls them “In-phase”

7. He calls them “Out-of-phase”

8. The voltage drop on capacitor lags in phase behind current.
