The standard unit of eletrical resistance is?
The standard measuring unit for resistance is ohm.
What is standard measurement of resistance?
ohms
Why do the standard resistance are made of magnin?
due to high resistance and low temprature coefficient

What are the standard units used to measure electrical resistance, commonly denoted as ohm units?
The standard unit used to measure electrical resistance is the ohm, denoted by the symbol .
Why magnet is used for making standard resistance coil?
magnet produce emf it maintain the resistance as same
Carbon resistors are not available in market of each number of resistance why?
carbon resistors of standard values are manufactured because other values can be obtained by series and parallel combination of standard values. Moreover even standard values do not offer exact Resistance's will have tolerance
What is a standard resistance?
A resistance standard is an extremely precise accurate resistor. They are typically used for calibration or laboratory purposes. They are commerically available from 100 microohms (0.0001 ohms) - 100 Terraohm (100,000,000,000,000 ohms) and are typically stable to 1-100 ppm per year for single value resistors depending on resistance and cost. See links for a commercial example of available resistance standards.
Why are alloys constantan and Manganin used to make standard resistors?
Constantan and Manganin have low temperature coefficients of resistance, meaning their resistance remains relatively stable over a wide range of temperatures. This makes them ideal for use in standard resistors where a consistent and precise resistance value is required. Additionally, both alloys have high resistivity, which allows for the creation of resistors with higher resistance values in a compact size.
What is the standard unit for resistance?
ohm
Why tunnel diode are used in negative resistance region?
because that the tunnel diode is a standard pn junction diode in many respect except its highly doped pn junction so it has some characteristics in the negative resistance region another that its a standard diode
What is the unit of measure for electrical resistance?
SI Units: Ohms Linesh Chungath India
