Electrical Calculations v2.31

Electrical Calculations does the following calcs.. Electrical Busbar, Cable, Powerfactor correction and motor starting calculations. The rating, dissipation and voltage drop of Aluminium and Copper Busbars can be calculated for any rectangular cross section. The rating and voltage drop of PVC cable is given for both metric and US cable sizes. Power factor correction capacitor sizing is calculated to provide the maximum correction that can be statically applied to an induction motor, this can be twice that shown in tables due to the variations in motor characteristics

DC Circuits Training

DC Circuits Training has 13 exercises to help you learn or
teach electricity or electronics. Covering series, parallel, and combinational resistive direct-current circuits, it uses random component values to create new exercises. As an added challenge, you must supply answers within a given tolerance.There's good online help available, and the sound
effects and visual reward gimmicks typical of educational software are tastefully done. Instant scoring and a built-in calculator and calendar round out an interesting and useful program.
