Reference these informational charts and choose the right nichrome and resistance wire to safely control the amount of current in your circuit.
Typically, nichrome is wound in coils to a certain electrical resistance, and when current is passed through it the Joule heating produces heat. Nichrome is used in the explosives and fireworks industry as a bridgewire in electric ignition systems, such as electric matches and model rocket igniters.
By winding Nichrome into coils with specific electrical resistance, heat can be generated by passing current through it. Simplify your calculations with our online Nichrome wire calculator, which allows you to effortlessly determine the resistance, power, current, and voltage of your Nichrome coil. Just input the length, thickness (between 10 ...
Nichrome wire exhibits a high resistance to electrical current due to its unique material properties. Its high resistivity, a measure of its opposition to current flow, makes it an ideal choice for heating elements, resistors, and other applications requiring controlled resistance.
Nickel-Chromium electric resistance wires: SWG - Imperial Standard Wire Gauge for sheet metal and wire. Example - Electric heater. Calculate the length of a nickel-chromium gauge 18 wire in an electric heater with power 2000 W, 230 V supply and max. wire temperature 500 o C. The current required to produce 2000 W can be calculated with Ohm's law as
The resistance of Nichrome wire is defined by its resistivity, a measure of how strongly the alloy opposes the flow of electric current. Nichrome’s typical resistivity ranges from 1.10 ×10 -6 to 1.50 × 10-6 ohm-meters, depending on the exact composition and manufacturing process.
Our nichrome wire has an appreciable temperature rating of 1177°C (2150°F), is corrosion resistant, and resists oxidation even at high temperatures. This resistance wire is suitable for use in heater wire applications (such as toasters) and cutting wire applications (such as foam rubber cutters).
The resistance \ ( R \) of a nichrome wire is calculated using the following formula: \ [ R = \frac {p \cdot L} {A} \] Where: \ ( R \) is the resistance in ohms (Ω) \ ( p \) is the resistivity of nichrome, approximately \ ( 150 \times 10^ {-8} \) ohm-meters. \ ( L \) is the length of the wire in meters.
Nichrome, a non-magnetic alloy that is commonly made up of 80% nickel and 20% chromium, has a resistivity ranging from 1.10 × 10 −6 Ωm to 1.50 × 10 −6 Ωm (0.00000110 Ωm to 0.00000150 Ωm) and a very high melting point (~1400 °C).
The resistance of a length of nichrome wire is measured using a digital multimeter as the length is increased. The results are plotted and the linear relationship between length and...
