REVISION OF FORMULAE
1.
Standard form of sinusoidally varying voltage
e
= Em sin ωt (or) v = Vm sin ωt
2.
em = ωNϕm
Where,
em = Maximum emf in volts
ω
= angular frequency in rad/sec.
N
= No of turns of the coil
ϕm
= maximum flux in webers
3.
ω = 2IIf = 2 II/T
Where
ω = Angular velocity in rad / sec
f
= Frequency in Hz or cps
T
= Time period in sec.
4.
RMS value of an alternating current I = 
5.
RMS value of an alternating
voltage 
6.
For a sinusoidal varying quantity,
RMS
value or effective value or virtual value = (1/√2) × Maximum value
=
0.707 Maximum value
7.
For regular shape of waveforms, say current wave form
8.
For irregular shape of waveforms
9.
For regular shape of waveforms
10.
Form factor K= RMS value / Average value.
11.
Peak factor (Ka) = Peak value / RMS value.
