The resistance of a conductor is directly proportional to the resistivity of the conductor. since the resistivity of a conductor is decreases with decrease in temperature hence the resistance.
ERMM THE RESISTANCE INCREASES ) when longer
Greek Resistance happened in 1941.
The current in the circuit will be decreased by half. Ohm's law states V=IR so, I=V/R. If R is doubled, then I= V/2R.
In what sense.
it increases
Super conductor will have zero resistance or zero resistivity. This happens when the temperature of the conductor reaches a very low temperature known as critical super conducting transition temperature. In case of mercury it will be 4.2K.
ERMM THE RESISTANCE INCREASES ) when longer
The resistance of a conductor normally increases with temperature. The increase in resistance is due to charged particles becoming more agitated and the number of particles going across a potential field at a given time period will be reduced (like in a traffic jam, the car engines are running but the cars are not going faster). The change in resistance per degree temperature change for a metal can be measured and are published.
If the lay ratio of a standard conductor is increased, resistance will diminish.
The system will rebalance.
It becomes more efficient. kapm
Take a look at Ohm's Law, usually written as V=IR. Solving for current: I = V/R. That means that a lower resistance will result in a larger current.
A load is anything that draws current from a source of potential difference. A 'heavy' load will draw a larger current than a 'light' load. A resistor can certainly be used as a load. A low resistance will draw a larger current than a higher resistance and, so, a low resistance represents a high load while a high resistance represents a low load.
Because of the second law of thermodynamics , law of entropy. "when energy flows from a high-temperature object to a low-temperature object, the source temperature is decreased while the sink temperature is increased; hence temperature differences tend to diminish over time."
When the temperature of a gas is increased at a constant pressure, its volume increases. When the temperature of a gas is devreased at constnt pressure, its volume decreases.
Because of the second law of thermodynamics , law of entropy. "when energy flows from a high-temperature object to a low-temperature object, the source temperature is decreased while the sink temperature is increased; hence temperature differences tend to diminish over time."
Current draw would increase proportionally, heating up the wiring and wearing more on the load pulling the power.
