    Silicon carbide, is used in hot surface igniters, which are heating elements designed for igniting flammable gas, are common in gas ovens and clothes dryers. Silicon nitride has been recently used as a surface igniter for gas furnace and diesel engine glow plugs. Such heating elements or glow plugs reach a maximum temperature of 1400 °C and ...

    A 2.26 kΩ, 1%-precision resistor with 5 color bands (), from top, 2-2-6-1-1; the last two brown bands indicate the multiplier (×10) and the tolerance (1%).. An electronic color code or electronic colour code (see spelling differences) is used to indicate the values or ratings of electronic components, usually for resistors, but also for capacitors, inductors, diodes and others.

    en.wikipedia.org/wiki/Heisler_Chart

    These first Heisler–Gröber charts were based upon the first term of the exact Fourier series solution for an infinite plane wall: (,) = = [⁡ + ⁡ ⁡], [1]where T i is the initial uniform temperature of the slab, T ∞ is the constant environmental temperature imposed at the boundary, x is the location in the plane wall, λ is the root of λ * tan λ = Bi, and α is thermal diffusivity.

  6. Joule heating - Wikipedia

    en.wikipedia.org/wiki/Joule_heating

    Joule heating is caused by interactions between charge carriers (usually electrons) and the body of the conductor.. A potential difference between two points of a conductor creates an electric field that accelerates charge carriers in the direction of the electric field, giving them kinetic energy.

  7. Ohmic contact - Wikipedia

    en.wikipedia.org/wiki/Ohmic_contact

    An ohmic contact is a non-rectifying electrical junction: a junction between two conductors that has a linear current–voltage (I–V) curve as with Ohm's law.Low-resistance ohmic contacts are used to allow charge to flow easily in both directions between the two conductors, without blocking due to rectification or excess power dissipation due to voltage thresholds.
