AC Circuits Flashcards
1
Q
What is the voltage of an AC circuit?
A
V(t)=V_0 cos(ωt)
2
Q
What is the complex representation for an AC circuit?
A
V(tilda)= V_0 exp(jωt)
3
Q
What is Ohm’s law for an AC circuit?
A
V(tilda)=Z(tilda) I(tilda)
Where Z is the complex impedance
4
Q
What is the impedance of a resistor?
A
Z=R
5
Q
What is the impedance of a capacitor?
A
Z=1/jωc
6
Q
What is the impedance of an inductor?
A
Z=jωL
7
Q
How do impedances in series add?
A
Z_eq=Z1+Z2
8
Q
How do impedances in parallel add?
A
1/Z_eq=1/Z1+1/Z2
