According to ohms law, V = IR,
where V=voltage
I= current
R = resistance
the above formula can also be written as I = V/R,
here, resistance is inversely proportional to current. In other words,
as resistance increases, current decreases.

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.
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 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 diameter of a conductor is doubled what happens to its resistance?
Resistance will decreases... Because R is inversely proportional to Area of the conductor.AnswerIf the conductor has a circular cross-sectional area, then doubling the diameter will reduce the resistance to one quarter of its original distance. This is because area is proportional to the square of the radius, and resistance is inversely proportional to cross-sectional area.
What happen if lay ratio of standard conductor is increase?
If the lay ratio of a standard conductor is increased, resistance will diminish.
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
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
If A conductor has a resistance of 0.8 ohms what will happen to its resistance if the temperature is increased?
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.
What is the relationship between insulation resistance and length of conductor in transformers?
when length is increased insulation resistance of cable is decresed i.e.,R is inversely proportional to L where R is resistance L is length
