Answer the following questions:
-
How does the author call the mathematical value which includes in itself effective value and the angular frequency?
-
How a capacitor looks like in a circuit with the source at low angular frequency?
-
How a capacitor looks like in a circuit with the source at high angular frequency?
-
What is the phase shift or voltage phasor in a circuit with capacitor?
-
According to the watched videos, how does the author calls the resistance which appears in circuit with capacitor or inductor?
-
How the author of the video calls the property of current and voltage to change its direction and effective value synchronously?
-
How the author of the video calls the property of current and voltage to change its direction and the effective value asynchronously?
-
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.
