Copper will.
Methane will flow most easily along a pipe because it is a gas at room temperature and has the lowest molecular weight of the compounds listed. This means that it will have the lowest viscosity and offer the least resistance to flow.
The lowest temperatures in polar climates can reach extreme lows, with Antarctica recording the coldest temperature on Earth at approximately -128.6°F (-89.2°C) at Vostok Station in July 1983. In the Arctic, temperatures can drop to around -50°F (-45°C) in winter. These frigid conditions are characterized by long, harsh winters and short, cool summers, contributing to the unique ecosystems found in these regions.
The short Version of the Definition of Weather is: temperature.
The lowest temperature for comfortable swimming in a pool typically ranges from 78°F to 82°F (25°C to 28°C). However, some people can tolerate temperatures as low as 70°F (21°C) for short periods. Below this range, water can feel uncomfortably cold, and prolonged exposure may lead to hypothermia. It's essential to consider personal comfort and safety when deciding on swimming conditions.
The copper is a good conductor of electricity. While the insulating plastic covering of the wire prevents bare wires touching and creating a short, or shocking (electrocuting) a person should the bare wire be touched with bare hands.
A short thick copper wire at low temperature would have lower resistance compared to a long thin iron wire at high temperature. This is because resistance is inversely proportional to cross-sectional area and directly proportional to temperature and length of the wire. The short thick copper wire has a larger cross-sectional area, which results in lower resistance.
The lowest resistance will occur in a situation where the material has high conductivity and short length.
Resistance in a wire can be reduced by using a thicker wire or a material with lower resistivity, like copper. Keeping the wire short and straight also helps reduce resistance. Additionally, ensuring good connections and minimizing temperature fluctuations can further decrease resistance.
No, resistance depends on the material, cross-sectional area, and temperature of the wire. A shorter wire will have less resistance compared to a longer wire since it offers less opposition to the flow of electrical current.
Yes, an inductor is a short circuit to dc...that's true....IF the inductor is an ideal one, that is, the inductor has no resistance but has inductance only. Anything in real world, as you know, is not ideal. An inductor is usually made of a copper wire. A copper wire has its own resistance. If an inductor coil is thin and long (i.e. many turns), it will provide an appreciable resistance to DC, and will no longer be a short circuit.
Resistance depends on the thickness and length of the wire used, as well as the conductor used. For example, a short, thick wire made of copper will conduct electricity better than a long, thin wire made of, say, iron.AnswerResistance is directly proportional to the length and inversely proportional to the cross-sectional area (not 'thickness') of a material. Its constant of proportionality is called resistivity which is affected by temperature -so temperature indirectly affects resistance.
The resistance of a wire is the length divided by the cross-section area and the conductivity of the material. So for small resistance you need a wire with short length, large cross-section area (diameter) and a material with high conductivity like copper.
Theoretically yes. However, there is always resistance through joints,components and trace impurities in wires. A dead short is only a dead short for an instant at a fixed temperature. As heat rises so does resistance. Consequently current falls. also, resistance of zero would violate the laws of thermodynamics, because it would imply zero entropy
When the reed switch is replaced with copper wire, the circuit becomes a closed loop with significantly less resistance compared to the reed switch. This lower resistance allows more current to flow through the circuit, including the bulb. The increased current flow results in the bulb glowing brighter as it receives more electrical energy.
There are too many:CostFlexibilityResistance to corrosionLess fittingsBetter resistance to freezingComes in continuous coils rather than 10ft short piecesLightweightEasier to install than copper and CPVC
no.because current always try to flow trough low resistance path.as short circuit has low resistance current pass trough short circuit
If the wire is short, its resistance will likely decrease. A shorter wire has less length for electrons to travel through, resulting in lower resistance according to the formula R = ρL/A, where R is resistance, ρ is resistivity, L is length, and A is cross-sectional area.
