Our Circuit Design Calculators for Engineers and Students are free-to-use tools that help you quickly determine key parameters ...

At other times it is less! To calculate the r.m.s. voltage from the peak voltage the factor of \(\frac{1}{\sqrt2}\) is used. Peak power is twice the r.m.s. power. \(Power=current\times voltage\).

Long cable runs can cause voltage loss, and compensating for that with larger cable dimensions comes at a cost. PVcase has developed a new solution to calculate expected voltage drop in different ...

Record voltage, current and diameter of the wire, d (supplied by the manufacture). Calculate resistance and cross section area, A, in mm 2 (A = \(\frac {{\pi }d^2}{4}\)). Plot a graph of ...
