**To Find Resistance of a wire using Metre Bridge and also**

d.c. Resistance: ? Note: To use different values for the Resistivity, select Enter Data in the Conductor Material selection text box and then enter the required values in the box highlighted in amber....Specific Resistance is a measure of the potential electrical resistance of a conductive material. It is determined experimentally using the equation ? = RA/l (Law of Resistance), where R is the measured resistance of some length of the material, A is its cross-sectional area (which must be uniform), and l …

**Temperature in a wire Physics Forums**

A 12-gauge wire is wider than 14-gauge wire and thus has less resistance. The lesser resistance of 12-gauge wire means that it can allow charge to flow through it at a greater rate - … how to get mew in fire red emulator EXP-4> To find resistance of a given wire using meter bridge and hence determine the specific resistance of its material. Materials Required: A meter bridge, galvanometer, one way key, a resistance box, a battery jockey, unknown resistance wire about 1 meter long, screw gauge and connecting wires..

## How To Find The Specific Resistance Of A Wire

### If l is the length of wire then the resistance per unit length of the wire = Fig -1 Circuit to find the relation between current (I )and potential difference(v)

- For example, RTD’s contain a sensing element which is manufactured to have a specific electrical resistance at a specific temperature. The most common example of this requirement is what’s known as the DIN standard. To meet the requirements of the DIN standard, an RTD must have a resistance of 100 Ohms – 0.12 % (or 0.12 Ohms) at 32°F (0°C) to be considered a Grade B sensor (a Grade A
- Resistance and Resistivity are both important concepts for electrical engineering. Resistance gives the ratio of the potential difference to current across a conductor at a given time, whereas Resistivity is the ratio of electric field to current density for a material at a specific temperature.
- 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.
- SPECIFIC RESISTANCE OR RESISTIVITY Specific resistance, or resistivity, is the resistance in ohms offered by a unit volume (the circular-mil-foot or the …
