The load-wiring-calculator will give you a very simple and quick solution to the problem of calculating the size of wires and DC maximum load for LED power transmission.

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. Please note this calculator assume the circuit is operate in a normal condition—room temperature.

## 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).
