How to Choose Spark Plug Wires
Oct 09 2015 Spiral Core Spiral core spark plug wires incorporate an alloy usually consisting of stainless steel copper and tin wrapping the core to suppress EMI/RFI while maintaining low resistance. As with everything there is a delicate balance. More wire coils around the core will reduce noise but raise resistance of the wire. Choosing Your Wire
Stranded Copper Wire or Solid Wire What to Choose
You must know the right gauge of wire. This is based on application and amperage load. This also decides what type of wire you must use copper aluminum nickel or other. Copper is usually the first choice but there are applications where aluminum works better. Again you must decide whether your application needs solid wire or stranded wire.

Choosing a Shielding Gas for Flux Cored Welding
Ionization potential is a measure of the energy required to ionize the gas i.e. transform to a plasma state in which it is positively charged enabling the gas to conduct current. The lower the number the easier it is to initiate the arc and maintain arc stability. The ionization potential for CO2 is 14.4 eV versus 15.7 eV for argon.

Conduction of Electrical Current to and Through the Human
Mar 21 2022 More than 99 of the body s resistance to electric current flow is at the skin. Resistance is measured in ohms. A calloused dry hand may have more than 100 000 Ω because of a thick outer layer of dead cells in the stratum corneum. The internal body resistance is about 300 Ω being related to the wet relatively salty tissues beneath the skin.
Electrical Wires for Use in Damp and Wet Locations
Jan 24 2010 The simplest way to determine whether a wire is suitable for damp or wet locations is to look for a W in the coding on the wire s insulation. This is easy to remember because the W essentially stands for wet. However there are some wires that are suitable for wet locations that don t carry a W in their coding.
