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.
Ohm's law: Voltage = Amperes * Ohms If you hold one of current or voltage constant, then increasing resistance would decrease current (holding voltage), or increase voltage (holding current).
If the voltage is unchanged, then the current will reduce.
Assuming that there is a potential difference across the conductor, then the value of the current will fall (I = E/R).
the voltage will drop
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.
The current decreases due to I=V/R. The ammeter reading will decrease as R is increased.
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.
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.
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.
If the lay ratio of a standard conductor is increased, resistance will diminish.
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 the lengh of the conductor is increased by 25%. find the increase in its resistance
ERMM THE RESISTANCE INCREASES ) when longer
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.
If Rotor resistance is increased torque is increased
it increases
If resistance is increased, current decreases. Ohm's Law: current equals voltage divided by resistance.
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

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.
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
