Let us consider a copper wire having radius r and length l. Let its resistance be R. If the radius of another copper wire is2rand the length isl/2then the resistance of this, wire will be View Solution Doubtnut is No.1 Study App and Learning App with Instant Video Solutions for NCERT...
Two wires one of copper and other of iron, are of the same length and same radius. Which will...Question:Two wires one of copper and other of iron, are of the same length and same radius. Which will have more resistance?The Resistance of ...
Two circular coils are made of two identical wires of same length and carry same current. If the number of turns of the two coils are 4 and 2, then the ratio
A new wire-junction node for modeling a junction with two wires of different radius using the TLM method is presented. The scattering matrix of the node is provided, and the numerical results are compared with the moment method solutions traditionally used for modeling wires and wirelike...
and intriguing properties, offer a competitive material platform for the fabrication of versatile biodevices [81,82]. To elucidate the advantages and characteristics of wearable devices based on 2D materials, this section is initiated with an introduction of the structural aspects of 2D materials, ...
Seunghwa Ryu2, Seung-Min Cho3, Nikhil Koratkar4,5 & Il-Kwon Oh1 The wettability of graphene on various substrates has been intensively investigated for practical applications including surgical and medical tools, textiles, water harvesting, self-cleaning, oil spill removal and microfluidic devices....
We suggest that this effect can be detected by measuring the degree of circular polarization of the edge luminescence in a nearby gapped material12, 13, 16, which ideally could be the same material with locally broken inversion symmetry. Tilted Dirac cones can be classified in to one of three...
For the WLD2, insert the needle so that it is between the two main wires on the plunger. Requires maintenance (excessive overtravel) Proper range Requires maintenance (insufficient overtravel) Proper range Requires maintenance (excessive overtravel) Cover Seal By using a pack...
Two balls aAandBof same size are dropped from the same point under gravity. The mass ofAis greater than that ofB.If the air resistance acting on each ball is same, then View Solution A body A of mass 4 kg is dropped from a height of 100 m. Another body B of mass 2 kg is droppe...
With phase-coherent beams, interferometric and even holographic microscopy could give new insight in conductance fluctuations and weak localization, as now individual or sets of trajectories can be selected without the need for permanent wires, instead of ensemble averaged. Along the same lines, we ...
