Formula Sheet — Alternating Current

Important formulas and equations from Alternating Current for Tripura JEE Physics.

Formulas — Alternating Current

AC Fundamentals

I = I_m sin ωt
I_rms = I_m / √2 = 0.707 I_m
I_avg = 2I_m / π = 0.637 I_m
ω = 2πν = 2π/T

AC in Resistor, Inductor, Capacitor

X_L = ωL = 2πνL
X_C = 1/(ωC) = 1/(2πνC)
V_L = I × X_L
V_C = I × X_C

LCR Series Circuit and Resonance

Z = √[R² + (X_L - X_C)²]
tan φ = (X_L - X_C)/R
I_m = V_m/Z
ω₀ = 1/√(LC)
Q = ω₀L/R = 1/(ω₀CR)

AC Power and Power Factor

P = V_rms × I_rms × cos φ
P = I²_rms × R
cos φ = R/Z
P = V²_rms/Z × cos φ
