Conductivity is the reciprocal of resistivity, and is expressed in siemens per metre (S/m). Resistivity and, therefore, conductivity vary with temperature so are usually quoted at a specified temperature.
Resistance is expressed in ohms. If you accurately measure the resistance, length, and cross-sectional area of a conductor, then you could determine its resistivity and, from that, its conductivity.
What else can I help you with?
What is the formula for finding ohms?
The formula for calculating resistance in ohms (Ω) is given by Ohm's Law, which states that resistance (R) is equal to voltage (V) divided by current (I). Mathematically, this is expressed as R = V/I, where R is resistance in ohms, V is voltage in volts, and I is current in amperes. This relationship helps to determine how much resistance is present in an electrical circuit.
What is the purpose for finding temperature coefficient of resistance?
to investigate change in resistance as temperature is varied
Creating a mnemonic device involves?
finding something familiar to represent something unfamiliar.
What TA make a good insulator?
Trapped air makes a good insulator.
What is the formula in finding the resistance?
For DC circuits: R = l*p / A R - resistance l = length of the conductor p = electrical resistivity A = the cross sectional area Calculating for AC, and especially three phase power becomes much more complicated. If you need to know more for AC, let me know specifics.
What do sparrow necklaces symbolize?
they represent freedom, or finding your true love.
What is the rule for finding the total resistance of a number of resistors connected in series?
If the resistors are in series, then the total resistance is simply the sum of the resistances of each resistor.
How do you test leakage on equipment?
by measuring the insulation resistance then by usig the formula for finding leakage current leakage current =voltage applied /resistance measured by megger.
Where to find an acting agent in California?
Finding one is easy. Getting one to represent you is hard.
How do you find a short in a car's electrical system?
Finding a short in a vehicle's electrical system usually involves isolating parts of the electrical system and looking or testing to see if the problem still exists.
Does you add the shorted resistors in finding the total resistance?
When resistors are wired in series, their resistances are added to find the total resistance. If they are run in parallel, or series-parallel, the formula is different
What is electrical shock sensation?
It is the hard way finding out that the electrical circuit is still energized. It is much easier on the body if a tester is used to check for voltage before any work is started on any electrical circuit.
