How long does it take at total charge of 10.0 C to pass through a cross-sectional area of a copper wire that carries a current of 3.1 A?
Here we are given 3.1 amperes of current and are asked to find the time it takes 10 coulombs of charge to pass a given point. First ask yourself how many coulombs are passing a given point in one second. If we have 3.1 amperes of current, we have 3.1 coulombs of charge passing any given point in one second. If it takes 1 second for 3.1 coulombs of charge to pass, how long will it take for 10C of charge to pass?
What is 6240000000000000000?
One ampere of curent is equal to the charge of 6,240,000,000,000,000,000 electrons flowing past a given point in a circuit per second.
When is static electricity come used?
Paint spraying cars: the paint particles are given a negative charge, and the car frame is given a positive charge, so the paint sprays out, and sicks to the car, and is attracted to all the hard- to reach areas Electrosatic precipitator; in coal fired power station theses are used to stop the dust particles reaching the atmosphere. Particles of ass pass through a charged grid, and becone charged. They then stick to plated either side of this grid, where they can be disposed of safely Photocopier; A charged drum is in the photocopier. Light is then shone through the paper, and whete ther is no print light hits the drum and it looses its charge. This leaves charge where there needs to be ink. Ink is the pulled onto the charged drum, and transfered onto paper Antistatic floors; to avoid static charges in hospital, the floors are made out of an antistatic material, so no charge can build up.

Which is faster to discharge or to charge a capacitor?
It depends on the amount of current available to charge or discharge. On the surface, I would say that you can discharge a capacitor faster than you can charge it, because the charge rate is limited by the current available in the power supply, while the discharge current could be quite high, because you could just apply a short circuit conductor around the capacitor. Of course, this could damage the capacitor. In truth, the equation of a capacitor is...dv/dt = i/C, which means that, given the same charge or discharge current, the rate of change of voltage would be the same.AnswerThe time taken to fully charge, or to fully discharge, a capacitor is given by the equation: time = 5 CR, where C represents its capacitance, in farads, and R represents the resistance of the circuit supplying the capacitor, in ohms. By 'fully charge', we mean bring the potential-difference across the capacitor's plates to the same value as the applied potential difference.If the external voltage source is replaced with a short circuit then, providing the resistance of the circuit hasn't changed, the discharge time will be exactly the same as the charging time. If the resistance is changed, then the same equation applies, but you need to insert the new value of resistance.
What is the definition for current intensity?
Current intensity refers to the amount of electric current flowing through a conductor in a given time, measured in amperes (A). It is a measure of the rate at which electric charge flows in a circuit.
What is the relationship between the electric field intensity (E), charge density (q), and permittivity of free space ()?
The relationship between the electric field intensity (E), charge density (q), and permittivity of free space () is given by the equation E q / (). This equation shows that the electric field intensity is directly proportional to the charge density and inversely proportional to the permittivity of free space.
How does electric field intensity form?
The electric field intensity is formed by the presence of electric charges. It is a vector quantity that represents the force experienced by a positive test charge per unit charge at a given point in space. The magnitude and direction of the electric field intensity depend on the distribution of charges in the vicinity.
What is the formula for calculating the electric field intensity at a distance r from a point charge q, given by E kq/r2, where k is the Coulomb's constant and r is the distance from the point charge?
The formula for calculating the electric field intensity at a distance r from a point charge q is E kq/r2, where k is Coulomb's constant and r is the distance from the point charge.
How do cyclones receive their names?
Tropical cyclones are named base on what part of the ocean then form in. Different regions are governed by different agencies with their own policies. Each ocean basin has a predetermined list of names. Every time a new system reaches a given intensity it gets the next name on the list. The intensity require for naming depends on what country is in charge of assigning names in a given area.
What is the intensity physics formula used to calculate the intensity of a given phenomenon?
The intensity physics formula used to calculate the intensity of a given phenomenon is I P/A, where I represents intensity, P represents power, and A represents the area over which the power is distributed.
What is the formula of wave intensity?
Not sure what formula you are looking for. Wave intensity is given by the amplitude of the wave.
In basketball what is a name given to long range shot in the last secounds of the game?
hail mary, just like ant other sport
What is current intensity?
Current intensity refers to the flow of electric charge through a conductor in a specific amount of time. It is measured in amperes (A) and represents the rate at which electric charges pass through a given point in a circuit. High current intensity can lead to overheating and damage to electrical components if not properly controlled.
What is the automobile's instantaneous velocity at time equals 60 secounds?
You haven't given enough info to answer the question. Do you know the acceleration? Did the car start from rest?
How to calculate the intensity of light in a given scenario?
To calculate the intensity of light in a given scenario, you can use the formula: Intensity Power / Area. This means that you divide the power of the light source by the area over which the light is spread to determine the intensity of the light.
The amount of energy that passes through a given point in a given amount of time is the?
intensity
