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.

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.
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 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 formula for finding probabilities?
The formula for finding probability depends on the distribution function.
Is the formula for finding the area of an oval the same as the formula for finding the area of a circle?
No because the formula for finding the area of an oval, which is an ellipse, is quite different
What is the formula in finding the reduced size wire if the resistivity is increased?
L1-L0=(RESISTANCE*AREA)/RESISTIVITY where L1=INIIAL LENGTH and L2=FINAL LENGTH
What is the formula for finding joules?
There isn't a formula for finding joules. It is a way for finding a force or giving an example.
What is the formula for calculating the resistance in an electrical circuit?
The formula for calculating resistance in an electrical circuit is R V/I, where R is the resistance, V is the voltage, and I is the current.
What is the formula for finding the area of an ellipse?
the formula for finding the area of an ellipse is add it then multiply and subtract that is the final
What is the formula of finding perimeter of a rectangle?
The formula for finding the perimiter of a rectangle is add up all of its sides
What is the formula for finding digital ammeter?
There is no formula for finding anything - except perhaps the inevitable "where was it when you last saw it?"
How do you calculate contact resistance?
Resistance is resistance , no matter if it is contact resistance or any other resistance. And formula is R = V / I.
