Can Alternating Current Be Converted to Direct Current?

A rectifier is an electrical device that converts alternating current (AC), which periodically reverses direction, to direct current (DC), which flows in only one direction. ... The process is known as rectification, since it "straightens" the direction of current.

Can AC be converted back to DC?

The most common way to convert alternating current into direct current is to use one or more diodes, those handy electronic components that allow current to pass in one direction but not the other. Although a rectifier converts alternating current to direct current, the resulting direct current isn't a steady voltage.

How do you convert AC current to DC current?

Write out the formula V_AC/√(2) and replace V_AC with the AC voltage you found with your multimeter. Use a calculator to solve your equation if you want the most precise answer. For example, if the AC power source has 120 V, then your formula would be 120/√(2) = 84.85 V in a DC signal.
