How to calculate electricity cost?

This part is important to us when suddenly our electricity cost is higher than normal usage.We can determine the figure from electrical supplier is correct or not

We also can calculated a electricity cost  for estimated our new electrical design such as install new motor,compressor,furnace or others equipment.With this calculation we can know the estimated of cost and can make a decision for that installation either it reasonable or not. read more

Alternating Current (AC)

What is an alternating current?

Alternating current (ac) is changing the current flow.Changes in the flow of current in ac circuits because if the changes the polarity of the alternating voltage source alternately.

Current value will increase from zero to a maximum in the positive direction and then dropped to zero. Next, the current will be reduced to a maximum in the negative direction. Then, the current back up to zero.
