Resistance of a conductor is the property by the virtue of which it opposes the current passing through it. If V is the potential difference applied across the two ends of a conductor, and a current I flows through it, the resistance of the condu...
To solve the problem, we will use the concept of Young's modulus and the relationship between stress, strain, and the properties of the wires.1. Identify Given Information for Wire 1: - Length \( L1 = L \) - Radius \( r1
Find the resistance (in mega Ω) of a wire of length 8 m, cross sectional area 2 cm2 and made of a material of resistivity 120 Ωm. View Solution What is the self-inductance of solenoid of length 31.4 cm, area of cross-section 10−3m2 and total number of turn 103? View Solution...
Resistance of the Wire:The resistance of a conducting wire depends on its geometry and its material. The resistance of a wire is expressed by as following; Resistance {eq}\ \ \ \ R = \dfrac{\rho \ L}{A} {/eq} Where; {eq}\boldsymb...

If you add a resistor to increase the total R, the resistor will the resistor itself will use a percentage of the total power equal to resistor's share of the total resistance of the wire and the resistor together. You should take that into account. ...
However, the dilemma can be resolved by considering that an appropriate length of wire also changes the current phase of the additional current path, which can actually help to reverse the effect of coupling. Another way to understand the phenomenon is that the entire compact terminal can be ...
