Parallel connection of resistors

Calculator gives the resistance of the resistor based on the introduced color bars.

Hydraulic cylinder is a mechanical akutatorem used for power transmission line by a linear thrust. Through the movement of the piston up and down over the forces and pressure. This calculator is used to calculate the two forces given angle for each operation.      

The calculator calculates the inductance of the coil without core on the basis of the given coil length, diameter and number of turns.                  

The calculator calculates the optimal surface for the heat sink temperature indicator.
