## How we calculate

#### Voltage Drop

This is a calculator for the estimation of the voltage drop of an electrical circuit based on the wire size, distance, and anticipated load current.

Voltage Drop = (WL x 2) x R x LC / 1000

Voltage Drop % = (Voltage Drop / SV) x 100

Where:
WL = Wire Length
R = Resistance
SV = Source Voltage

#### Max. Wire Length

Calculates the maximum wire length of a single round wire of common conducting materials using the formula below.

Wire Length = ( VD x 1000) / (LC x 2 x R)

Where:
VD = Voltage Drop
R = Resistance

The resistance is then matched to the corresponding wire gauge value as per the American Wire Gauge standard (AWG).

#### Suitable Wire Gauge

Calculates the Resistance of a single round wire of common conducting materials using the formula below.

Resistance = (VD x 1000) / (2 x WL x LC)

Where:
VD = Voltage Drop
WL = Wire Length

The resistance is then matched to the corresponding wire gauge value as per the American Wire Gauge standard (AWG).
