Induction Formulas Flashcards
0
Q
Total impedance.
A
Z = √R² + XL²
1
Q
Inductive reactance.
A
XL = 2π∱L
or
XL = 6.28∱L
3
Q
Voltage drops across various components in inductive circuits
A
VL = IL x RL for inductive components
Vr = Ir x Rr for resistive “
V? = I? x Z? for impedance “
Etc.
4
Q
Total current.
A
It = V ÷ R
5
Q
Power Factor.
A
PF = R/Z
6
Q
Power
A
W = V x I x PF
7
Q
Frequency.
A
∱ = 1/period (of time)
8
Q
Phase angle.
A
∠θ ➡️ cos θ = R/Z
