How to Calculate Resistance Using Resistivity Step 1: Identify the resistivity (ρ), length (L), and radius (r) of the wire. Step 2: Calculate the cross-sectional area of the wire using the formula for the area of a circle: A=πr2. Step 3: Calculate the resistance (R) of the...
StrandedLoss is dependent on the object’s material conductivity of a stranded source. It represents the loss due to the DC resistance only and uses the cross-sectional area of the object that is assigned with the excitation. Where J is the current density, it is calculated by...
Based on the problem, we are given the number of loops, 900, the cross-sectional area of the wire, 0.08 m, and the length of the wire, 9.0 m. Step 2:Use the equation, {eq}L = \frac{{\mu}N^{2} A}{l} {/eq}, to calculate the inductance of a solenoid. ...
The value obtained by dividing this repelling force by the cross-sectional area (the value converted to per unit area) is called “stress” (σ). With the external pulling force as P (N) and the cross-sectional area as a (m2), the stress is obtained as follows. ...
When selecting the conductor cross section of the electrical power cable, it is necessary to calculate the current carrying capacity of the conductor. For 380VAC power supply equipment, the formula for calculating the current is as follows: I=P/1.732/U/cosΦ, I-equipment rated current (A), ...

Find the conductance of a round piece of iron with a cross-sectional radius of 0.001 meters and length of 0.1 meters. Iron has a conductivity of 1.03 × 107siemens/m, and the cross-sectional area of the wire is 3.14 X 10-6m. The conductance of the wire is then 324 siemens. ...
The cross-sectional shape of wires can be round or rectangular (ribbons). Thin wires are wires up to 75µm diameter (3 mil). Beyond that size, we speak about thick wire testing. The material of the wires or ribbons is mostly gold, aluminum, copper, or silver. It is possible to tes...
where Q is the velocity of air or its flow rate, A is the cross-sectional area across which the air under study is flowing, and V is the linear velocity of the air, i.e., the average speed at which a given air molecule is moving along in the stream. ...
Find the second moment of area about the vertical axis for the cross-section of the follwing shape. i can't get the pic to paste so will describe it...
