What else can I help you with?
If pressure is constant and current increases the resistance?
I assume you meant pressure to voltage. The resistance of a conductor is directly proportional to the temperature of the conductor. If the temperature of the conductor increases due to increased current, then the resistance tend to increase too.
What will happen to the ammeter reading if the resistance is increased?
The current decreases due to I=V/R. The ammeter reading will decrease as R is increased.
What happens to resistance when increasing cable length?
this is because there will be more collisions between atoms and electrons as there is a greater distance to travel. The longer the length of wire, the more collisions. It is like a traffic jam, the longer the road, the loner you are stuck in it for.
When the length is increased 2 times the value for resistivity will be?
The value for resistivity will remain unchanged (provided temperature remains constant). Resistivity is a property of the material. The resistance, however, will double. Remember that resistance is directly proportianal to the length of the conductor and inversely proportional to the cross-sectional area of the conductor.
What causes resistance to increase or decrease?
Voltage, if voltage is increased resistance in the circuit increasesAnswerResistance is determined by the length, cross-sectional area, and resistivity of a conductor. Resistivity is, in turn, affected by temperature -so temperature indirectly affects resistance.These are the only factors that affect resistance. Voltage and current have no direct effect whatsoever on resistance. Current can affect resistance indirectly if it causes the conductor's temperature to increase.For AC circuits, 'skin effect', due to frequency, causes the current to flow towards the surface of a conductor which acts to reduce the effective cross-sectional area of that conductor. So, frequency can also indirectly affect resistance.
How can the current in a conductor be increased?
The current in a conductor can be increased by either increasing the voltage applied across the conductor or decreasing the resistance of the conductor.
If A conductor has a resistance of 0.8 ohms what will happen to its resistance if the temperature is decreased?
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.
When length is increased by 25 percent than find percent increased in resistance?
when the lengh of the conductor is increased by 25%. find the increase in its resistance
What will happen to the resistance if the length of the conductor increase?
ERMM THE RESISTANCE INCREASES ) when longer
What is different hot and cold conductor?
A conductor has low electrical resistance when hot and higher electrical resistance when cold. This is due to the increased thermal agitation of electrons in the conductor when it is hot, causing higher resistance compared to when it is cold.
If pressure is constant and current increases the resistance?
I assume you meant pressure to voltage. The resistance of a conductor is directly proportional to the temperature of the conductor. If the temperature of the conductor increases due to increased current, then the resistance tend to increase too.
What will happen to speed-torque characteristics of an induction motor is the rotor resistance is increased?
If Rotor resistance is increased torque is increased
What happen to resistance if length is increased?
it increases
What happen to the current in a circuit if the resistance is increased?
If resistance is increased, current decreases. Ohm's Law: current equals voltage divided by resistance.
Why does resistance of a conductor rise with temperature?
When the temperature of a conductor is increased, the amplitudd of vibrations of atoms increases.As a result, the probability of collision of electrons with vibrating atoms increases.That is why, it is said that the resistance of a conductor is increases with increasing temperature
Why the resistance of conductor rise with the rise of temperature?
When the temperature of a conductor is increased, the amplitudd of vibrations of atoms increases.As a result, the probability of collision of electrons with vibrating atoms increases.That is why, it is said that the resistance of a conductor is increases with increasing temperature
What happen if lay ratio of standard conductor is increase?
Increasing the lay ratio of a standard conductor means increasing the length of lay, which can result in reduced flexibility and increased overall diameter of the conductor. This can impact the handling and installation of the conductor. Additionally, it can affect the electrical performance by increasing inductance and potentially introducing more losses due to skin and proximity effects.
