The henry (symbol: H) is the unit of electrical inductance in the International System of Units (SI). [1] If a current of 1 ampere flowing through a coil produces flux linkage of 1 weber turn, that coil has a self-inductance of 1 henry. The unit is named after Joseph Henry (1797–1878), the American scientist who discovered electromagnetic induction independently of and at about the same ...
Atco is the trade name for lawn mowers derived from the Atlas Chain Company, founded by Charles Henry Pugh in 1865, which made chains for ships. [1] [2]Mowing machines (replacing scythes) were drawn by horses but, after a horse died while pulling a mower around his company's facility, Pugh created a petrol lawnmower, which became the first of its kind to be mass-produced anywhere in the world.
Resistance ribbon heating elements are made by flattening round resistance wire, giving them a rectangular cross-section with rounded corners. [8]: 54 Generally ribbon widths are between 0.3 and 4 mm. If a ribbon is wider than that, it is cut out from a broader strip and may instead be called resistance strip. Compared to wire, ribbon can be ...
If the resistance is not constant, the previous equation cannot be called Ohm's law, but it can still be used as a definition of static/DC resistance. [4] Ohm's law is an empirical relation which accurately describes the conductivity of the vast majority of electrically conductive materials over many orders of magnitude of current.
An induction coil consists of two coils of insulated wire wound around a common iron core (M). [1] [7] One coil, called the primary winding (P), is made from relatively few (tens or hundreds) turns of coarse wire. [7] The other coil, the secondary winding, (S) typically consists of up to a million turns of fine wire (up to 40 gauge). [8] [1] [7]
Nichrome, a non-magnetic 80/20 alloy of nickel and chromium, is the most common resistance wire for heating purposes because it has a high resistivity and resistance to oxidation at high temperatures, up to 1,400 °C (2,550 °F). When used as a heating element, resistance wire is usually wound into coils.
