Visit BYJU’S to understand the relation between Resistance and Length along with Resistance and Length formula, units, definition, problems, and resistivity formula.
Suppose L is the length of the wire, A is the cross-section area of the wire and ρ is the resistivity of the material, then we can defined the relation that is given by: R=ρ LA where A=π r2Answer and Explanation: Given: The length of the ...
The resistance of a wire is directlyproportional to its lengthand inversely proportional to its cross-sectional area. Resistance also depends on the material of the conductor. ... The resistance of a conductor, or circuit element, generally increases with increasing temperature. Does resistance depend...
Then cut the sample into two equal parts and compressing the two equal parts with mechanical pressure. Again, resistance is measured. By assuming that the length of material is not changed, the measured resistance will always be larger than the initial value. The reason for this increased ...
Principle of operation (b) With most metals a rise in temperature causes an increase in electrical resistance, and since resistance can be measured accurately this property can be used to measure temperature. If the resistance of a length of wire at 0°C is and its resistance at 0°C is ...
A key difference that exists between the MPPF and the wire is that due to geometry, the stray capacitance and inductance of the film may have an effect on plasma formation. Tests have been performed on three types of MPPF to determine a relation, if any, between the impedance of the film...
What is the resistance of a conductor ? State the factors on which resistance of a conductor depends? How is it related to conductivity of the conductor? View Solution How does the resistance of a conductor depend on: (a) length of the conductor?
So your question cannot be answered because it is improperly asked; although a length of wire might exhibit a resistance of 0.04328 Ohms for each meter of its length, please carefully study the thread and figure out what is wrong with your question, and I think the answer will come to you...
The immersion depth for long stem SPRTs is large, in part because of the precision required and in part because of the length of the sensing element. Adequate immersion depths are typically 0.2m at room temperature and up to 0.3m at temperatures greater than 200°C. The magnitude of any ...
relation given approximately byV= 30 + 10/I+l[1+ 3/I]103for a currentIin an arc lengthlmetres. The expression is roughly equivalent to 10 V/cm for large currents and high voltages. The current density varies between 1 and 1000 A/mm2, being greater for large currents because of the...
