Resistance can be calculated using Ohm's Law, which states that resistance (R) is equal to the voltage (V) across a component divided by the current (I) flowing through it: ( R = \frac{V}{I} ). Additionally, in a circuit with multiple resistors, total resistance can be calculated using series and parallel formulas. For resistors in series, the total resistance is the sum of individual resistances, while for resistors in parallel, the total resistance can be found using the formula ( \frac{1}{R_{total}} = \frac{1}{R_1} + \frac{1}{R_2} + \ldots ).
You have to measure the voltage, and the current. The resistance is then calculated by using Ohm's Law.
what is the diference betwean calculated and maesured value
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. 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.
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
Ohm's Law is stated as V=I*R, where V = voltage, I = current, R = 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
A meter bridge is used to measure an unknown electrical resistance by comparing it with a known resistance. It works on the principle of Wheatstone bridge. By balancing the bridge circuit, the value of the unknown resistance can be calculated accurately.

without knowing resistance this cannot be calculated
Yes, there may be differences between measured and calculated values of resistance. Measured resistance is obtained through direct measurement using a multimeter or other relevant instruments, while calculated resistance is determined using Ohm's Law based on the circuit components. Factors such as temperature, component tolerances, and measurement errors can lead to discrepancies between the two values.

Your hair dryer has a resistance of 220/12 = Ohms. (I'm sure you can do the math.)
ohms law calculation for a series circuit - Total Resistance = Total Voltage divided by Total Current
Resistance is calculated using Ohm's Law, which states that resistance (R) is equal to the voltage (V) across a circuit divided by the current (I) flowing through it, R = V/I. Resistance can also be determined using the color bands on a resistor in a circuit by referring to a resistor color code chart.
