### Formula

Here are the electrical formulas used in the above calculator,

Ohm's Law: V = I * R

Voltage (V): The product of current (I) and resistance (R).
Resistance (R) Calculation:

R = (2 * res * len) / a

res: Resistance of the selected wire type.
len: Length of the wire.
a: Cross-sectional area of the wire.
Voltage Drop (Vd) Calculation:

Vd = I * R

Vd: Voltage drop across the wire.
I: Current flowing through the wire.
R: Resistance of the wire.
Percentage of Voltage Drop (Vdp) Calculation:

Vdp = (Vd / V) * 100

Vdp: Percentage of voltage drop.
Vd: Voltage drop across the wire.
V: Input voltage.
Voltage at the End (Vend) Calculation:

Vend = V - Vd

Vend: Voltage at the end of the wire.
V: Input voltage.
Vd: Voltage drop across the wire.
Power Loss Calculation:

PowerLoss = (Vd * Vd) / R

PowerLoss: Power loss in the wire.
Vd: Voltage drop across the wire.
R: Resistance of the wire.
Maximum Allowable Current Calculation:

MaxCurrent = (V * 0.03) / R

MaxCurrent: Maximum allowable current for the wire.
V: Input voltage.
R: Resistance of the wire.
