**Nichrome Wire Calculator Jacobs Online**

For each wire plot a graph of resistance (y-axis) against length. The resistance of a wire is given by the equation: R = ? x l/A Where R is resistance, ? (pronounced 'rho') is the resistivity of the wire, l is length and A is its cross-sectional area.... the wire is folded in half and both halves are used to conduct electricity? A tungsten rod and an aluminum rod have the same length and resistance. What is the ratio of the cross sectional area of the tungsten rod to the aluminum rod?

**Electric Resistance Problems â€“ The Physics Hypertextbook**

Electrical resistivity (also known as specific electrical resistance) is a measure of how strongly a wire opposes electric current. A low resistivity indicates a wire that readily allows the movement of electrical charge. Copper has a resistivity of 0.0171 Ohm... the wire is folded in half and both halves are used to conduct electricity? A tungsten rod and an aluminum rod have the same length and resistance. What is the ratio of the cross sectional area of the tungsten rod to the aluminum rod?

**Resistivity of Carbon Graphite The Physics Factbook**

Calculate the end-to-end resistance of a 20 meter length of copper wire with a diameter of 0.05 cm. Use 1.678?10 ?6 ?·cm for the speci?c resistance of copper. ?le 01483 how to grow black raspberries from seed Find the resistance of the other wire? is done on EduRev Study Group by Class 12 Students. Length, diameter and specific resistance of two wires of different materials are each in the ratio of 2:1. One of the wires has a resistance of 10 ohm.

**Resistance and Resistivity Engineering ToolBox**

Resistivity and Conductivity. The electrical resistance of a wire would be expected to be greater for a longer wire, less for a wire of larger cross sectional area, and would be expected to depend upon the material out of which the wire is made. how to find lost childhood friend Since it is temperature dependent, it can be used to calculate the resistance of a wire of given geometry at different temperatures. The inverse of resistivity is …

## How To Find The Specific Resistance Of A Wire

where, R is known resistance placed in the left gap and unknown resistance X in the right gap of metre bridge. I cm is the length of metre bridge wire from zero end upto balance point. For Specific Resistance Cut the resistance wire at the points where it leaves the terminals, stretch it and find

- Use this calculator to find the right nichrome wire size, length and power supply for your application. There are four variables involved in determining what you need: voltage, gage, length, and temperature.
- 19/02/2018 · Because you want to calculate the resistance of the wire, you will need to rearrange the equation to solve for resistance. This yields R = V/I. If you experimentally determine the amount of current and voltage going through the wire, you can calculate the resistance.
