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.      

Calculator in supply capacitor, the capacitance and load resistance calculates the energy stored in the capacitor and the time constant of the RC circuit.
