We can find it by using wheatstone bridge.
A: the resistance should be decreased to 1/2 its value for half scale reading or use any ratio [ decrease] to obtain a correct reading.
The half deflection method is called so because it involves measuring the deflection of a beam or structure at a midpoint, typically at half the span of the element. This approach allows engineers to evaluate the structural behavior and performance under load conditions by analyzing the deflection at this critical point. The term "half" signifies the specific location where the deflection is observed, which is crucial for calculating bending moments and ensuring structural integrity.
if f is applied on L length sprig it will deflect by x distance. When spring is L/2 deflection is also x/2 for same force f.. and K=F/deflection. there for k is inversaly proptional to deflection .. when deflection is half K is double.
The resistance of a wire is directly proportional to its length, so if the length is reduced by half, the resistance will also be reduced by half.
half inch of upper chain deflection
less than half an inch along the longest stretch
one of them is the creaming method
If the length of the conductor is halved, the resistance of the conductor also decreases by half. This is because resistance is directly proportional to the length of the conductor. Shortening the length leads to fewer collisions between electrons and reduces the overall resistance.
Assuming you are asking "How does resistance altercurrent?", then the answer is that, for a given value of potential difference, the current is inversely-proportional to the resistance. E.g. doubling the resistance will reduce the current by half.
advantages of split half reliability
Double the area means half the resistance. Resistance = resistivity times length / area. Resistivity is a property of the material only.
The radiation resistance of a half-wave folded dipole is typically around 300 ohms. This value is higher compared to a regular half-wave dipole due to the increased current distribution along the folded elements.
