You can measure it, but you can't calculate it. That's why the resistance of a
resistor is always printed on it, either in numbers or in color bands. Without that
marking, the resistor is pretty useless. If it accidentally missed being marked
during manufacture, it would be either discarded, or sold surplus for bubkes.
Potential difference, V = Current, I x Resistance, R
So rearranging the equations gives
Potential difference/Current = resistance
Resistance (Ohms) = Potential Difference (Voltage) / Current (Amps)
footing resistance is that resistance which could not harm human body while touching tower...and it is calculated by earth resistance tester
what is the diference betwean calculated and maesured value
You have to measure the voltage, and the current. The resistance is then calculated by using Ohm's Law.
The specific resistance of the material can be calculated
without knowing resistance this cannot be calculated
yes , there is a difference because there is a tolerance
The series resistance is 4 x 50 = 200 Ohms. You would need additional information to get the current; usually this is calculated from the voltage. current = voltage / resistance.The series resistance is 4 x 50 = 200 Ohms. You would need additional information to get the current; usually this is calculated from the voltage. current = voltage / resistance.The series resistance is 4 x 50 = 200 Ohms.

ohms law calculation for a series circuit - Total Resistance = Total Voltage divided by Total Current
Ohm's Law is stated as V=I*R, where V = voltage, I = current, R = resistance.
In electronics, R or resistance is calculated by dividing the voltage by the current, or I/E Here's a good Ohms law chart; http://www.the12volt.com/ohm/ohmslaw.asp
