5. Electrical Strength Law
Given the power symbol and the letter P in Watt. Ohm's law formula can be written for the equality of power, namely:
P = U x I
Where : P = Power in Watt
U = Voltage in Volt.
I = Currents in Ampere

Right Value
Value wave voltage can be in writing:
V = Em Sin ωt
This price is the value right, in the notation with a small letter. For AC currents, the value right with:
i = Im sin ωt
e = Em sin ωt

7. Description: i = current rates as soon e = value right voltage
Im = Maximum Flow Rates (Peak)
Em = Value Maximum Voltage (Peak)
sin ωt = Corner of the applied wave

8. Vef = effective voltage (V) Vm = maximum voltage (V)
Effective Value
Vef = effective voltage (V)
Vm = maximum voltage (V)
ief = effective flow (A)
im = maximum flow (A)
