the length plays an important role while maintaining the resistance value. In a conducting material if the length of the wire is so long then it has a large number of free electrons in it. So these electrons will get enough kinetic energy when they got sufficient...
The Second Law states that ” the conducting material is inversely proportional to the cross-sectional area of the material”. According to this law, its material increases with the decrease in the cross-sectional area of the conductor and decreases with an increase in the cross-sectional area. ...
Resistance is a physical property of any conducting material. It opposes the flow of electric current. Resistance is temperature-dependent, for conductor it increases with increases in temperature whereas for semiconductor material it decre...
A resistor in a simple circuit is shown in Fig. 1.2. We represent a resistor by its standard zig-zag symbol, as illustrated in Fig. 1.4. Low-resistance resistors which often have to dissipate power in the multiple watts range are usually wire-wound, whereas the more common, higher-resistan...
A conducting wire is drawn to 4 times its length and one half its radius. By what factor is its resistance increased? A gold wire is 4.5 m long and 0.45 mm in diameter. What is its resistance? A wire has a resistance of 0.024 \Omega . What will the wire's resista...

Formula: R = ρL/A Where: ρ - Resistivity constant of the material, in Ω·m L - Length of the wire, in meters A - Cross-sectional area of the wire, in m² R - Resistance, in ohms (Ω) Thank you for your support. Please visit nitrio.com for more apps for your iOS device...
(1958)where the sensing elements were all connected to oscillators that converted the measured variables toaudio frequenciesthat could then be sent to the surface via a single conducting element in the profiler support cable. The outer cable sheath acted as both mechanical support and the return ...
Once an electric current is supplied throughout a conducting wire to reach the destination but due to some reasons, there is a loss in electric current along the way. Thus we need to perform the insulation testing to verify if there is any current leakage because this leakage could be very...
It is defined as a measure of how strongly amaterialopposes the flow of electric current. The resistance of the conducting wire depends on the material of which wire is made. Every conductor has its own resistivity. Resistivity is denoted by the letter ρ. ...
