STEP 0: Pre-Calculation Summary
Formula Used
Resistance = (Final Resistance*Length^2)/((Final Length)^2)
R = (Ω*L^2)/((l2)^2)
This formula uses 4 Variables
Variables Used
Resistance - (Measured in Ohm) - Resistance is a measure of the opposition to current flow in an electrical circuit. Its S.I unit is ohm.
Final Resistance - (Measured in Ohm) - Final Resistance is a measure of the opposition to current flow in an electrical circuit. Resistance is measured in ohms, symbolized by the Greek letter omega (Ω).
Length - (Measured in Meter) - Length is the measurement or extent of something from end to end.
Final Length - (Measured in Meter) - Final Length is the measurement or extent of something from end to end.
STEP 1: Convert Input(s) to Base Unit
Final Resistance: 50 Ohm --> 50 Ohm No Conversion Required
Length: 1500 Millimeter --> 1.5 Meter (Check conversion here)
Final Length: 1200 Millimeter --> 1.2 Meter (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
R = (Ω*L^2)/((l2)^2) --> (50*1.5^2)/((1.2)^2)
Evaluating ... ...
R = 78.125

8 Resistance Calculators

Temperature Dependence of Resistance
Go Resistance = Resistance at Reference Temperature*(1+Temperature Coefficient of Resistance*Change in Temperature)
Resistivity of Material
Go Resistivity = (2*[Mass-e])/(Number of Free Charge Particles per Unit Volume*[Charge-e]^2*Relaxation time)
Internal Resistance using Potentiometer
Go Resistance = (Length-Final Length)/Final Length*Final Resistance
Resistance
Go Resistance = (Resistivity*Length of Conductor)/Cross-Sectional Area
Resistance on Stretching of Wire
Go Resistance = (Final Resistance*Length^2)/((Final Length)^2)
Resistance of Wire
Go Resistance = Resistivity*Length/Cross-Sectional Area
Equivalent Resistance in Parallel
Go Equivalent Resistance = (1/Resistance+1/Final Resistance)^(-1)
Equivalent Resistance in Series
Go Equivalent Resistance = Resistance+Final Resistance

Resistance on Stretching of Wire Formula

Resistance = (Final Resistance*Length^2)/((Final Length)^2)
R = (Ω*L^2)/((l2)^2)

How is resistance of wire calculated when length of wire is increased ?

When a wire is stretched keeping volume constant then the formula of resistance is calculated through the formula R1 = R2 l12 / l2
where R1 is the initial resistance , R2 is the resistance when length of wire is increased , l1 is the initial length and l2 is the length after length of the wire is increased.

How to Calculate Resistance on Stretching of Wire?
