What is the maximum amount of current a conductor can carry continuously without exceeding its temperature ratings?
The maximum amount of current a conductor can carry continuously without exceeding its temperature rating is typically determined by the conductor's ampacity rating, which is based on factors such as the conductor material, insulation type, and ambient temperature. It is important to adhere to these ampacity ratings to prevent overheating of the conductor.

How do you calculate the amount of current a conductor can carry?
The amount of current a conductor can carry is determined by factors such as the material, size, and temperature of the conductor. It is calculated using Ohm's Law (I = V / R), where I is the current, V is the voltage, and R is the resistance of the conductor. The conductor's ampacity rating also provides guidance on the maximum current it can safely carry without overheating.
Does an electric current move a short distance and then stop?
No, an electric current flows continuously in a closed circuit. The movement of charges (usually electrons) through the conductor allows the flow of current to persist until the circuit is broken.
What factors determine the size of a current?
The size of a current is determined by the voltage applied, the resistance of the circuit, and Ohm's Law (current = voltage / resistance). The type of conductor material used, the temperature, and the cross-sectional area of the conductor also affect the size of a current.
When current passes through a conductor what makes the conductor heat up?
When current passes through a conductor, the electrons in the conductor collide with the atoms, creating resistance. This resistance causes the electrons to lose energy in the form of heat, which increases the temperature of the conductor.
What affects the amount of current that can go through a wire?
1. The potential difference given to the conductor 2. The resistance of the conductor 3. The change in magnetic field linked with the conductor 4. The temperature of the conductor 5. The material that we have chosen as the wire
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.
Why the temperature increases as current increases?
The current is the flow of electrons. Temperature is the movement of atoms. As the current increases there is more collisions between the atoms and the electrons. Some of the energy from the electrons is transferred to the atoms, thus they move faster and so the temperature increases.

What is the current carrying capacity of ACSR conductor at 45 degree ambient?
The current carrying capacity of an ACSR conductor is typically specified by the manufacturer and depends on factors such as conductor size, insulation type, and ambient temperature. Operating at a 45-degree ambient temperature may lead to a slight derating of the conductor's current carrying capacity compared to standard conditions, so it would be best to consult the manufacturer's specifications for accurate information.

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.
Which semiconductor have positive temperature coefficient?
With the increase in temperature if the resistance increases or the current in the circuit decreases then it is said to be have positive temperature coefficient .But in semi-conductors with the increase in temperature the electrons present in the valance band are excited and they would enter the conduction band for conduction . As the no. of charge carriers always increase in a semi-conductor , implies that the current always increases with the increase in temperature so the semi-conductor can never have positive temperature coefficient
What will be Heat developed in current carrying carrying conductor?
Any conductor has resistance. Maybe not much, but there's always some.Any resistance dissipates power, at the rate of I2R. (I = current through it, R = its resistance.)That's how you build toasters.
How much current you can take from 10sqmm cu conductor?
The current carrying capacity of a 10sqmm copper conductor depends on factors such as ambient temperature, insulation type, installation method, and conductor grouping. As a general guideline, for typical installation conditions, a 10sqmm copper conductor can carry around 40-50 amps of current. It is important to consult with local electrical codes and standards for precise values.
