electric rectifier?

Question

I have a small job like chrome plating for metal made bracelet or watches that i wanted to have it plated. I wanted a rectifier that would suit my budget.

Answer 1

Any small rectifier and transformer should be fine for something as small as a bracelet. Silicon diodes such as the 1N400x series cost a few cents and can handle 1 Amp.
A small battery charger would also do, even a 500 mA trickle charger. You could even use a 6-volt lantern battery. A current of ~4 mA per CM^2 (~20 mA/sq. in.) is all that's needed, and precious metals such as gold may be plated by displacement (no electricity needed). Use a series resistor to prevent damage to the rectifier, transformer and jewelry if a short should occur.
To get smooth, shiny plating, the electrolyte is important. Various materials are added to CuSO4, NiSO4 etc. to make the plating adhere better and more smoothly such as borates, gelatin etc.
Careful! Most plating solutions are poisonous and/or allergenic, and many attack metal containers.

Answer 2

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.
Rectifiers have many uses, but are often found serving as components of DC power supplies and high-voltage direct current power transmission systems. Rectification may serve in roles other than to generate direct current for use as a source of power. As noted, detectors of radio signals serve as rectifiers. In gas heating systems flame rectification is used to detect presence of a flame.

Because of the alternating nature of the input AC sine wave, the process of rectification alone produces a DC current that, though unidirectional, consists of pulses of current. Many applications of rectifiers, such as power supplies for radio, television and computer equipment, require a steady constant DC current (as would be produced by a battery). In these applications the output of the rectifier is smoothed by an electronic filter (usually a capacitor) to produce a steady current.

More complex circuitry that performs the opposite function, converting DC to AC, is called an inverter.

A car battery charger takes an AC source and gives a constant 12V output, you can vary the current output by choosing your own resistance to give the required current density for electroplating. Otherwise, mose electronic shops will sell "Lab Power Packs" which allow you to vary volts and current...In Australia these cost between $50-$200 depending on the required capacity
