18K RGP stamped on a bracelet signifies '18 karat rolled gold plate.' This indicates a thicker layer of gold bonded onto a base metal, offering higher durability than regular gold plating. However, its value remains primarily associated with the base metal beneath the gold layer.
Jewelry engraved with RGP, which stands for Rolled Gold Plating, or plaqué d'or laminé, (proper designation: 1/30 14 kt.), contains approximately 100 times the average amount of gold utilized in gold plating (which is either sprayed or dipped). Rolled Gold Plating involves the lamination of a thin sheet of gold leaf with a lesser metal (usually brass), fused by heating under pressure.

6 separate 18kOhm resistors wired in series make a total resistance of:18k+18k+18k+18k+18k+18k which is 108 kOhm.6 separate 18kOhm resistors wired in parallel make a total resistance of:1/[(1/18k) + (1/18k) + (1/18k) + (1/18k) + (1/18k) + (1/18k)] which is 3 kOhm.
10k rgp means 10 karat gold rolled gold plate. In other words, it's gold PLATED.
