i need help with a science question please help me?

Question

What is a volt and what is an amp?

i need answers to do with electrons and stuff like that which is to do with the current (amp) but i dont know how to answer properly for amps and i have forgotten what a volt is

Answer 1

Amps is the Flow of electricity
Ohms is the resistance of electricity
Volts is the pressure of the electrical current.

Hope this is what you needed

Answer 2

Simply: Volts are push and amps are electrons.

Volts push electrons, the higher the voltage the greater the push.
If you were to grab a high voltage (only voltage) it would throw you back. They are named after Alessandro Volta .

Amps are the number of electrons that pass a point in a second. usually they are in 1000's, so a 15 amp circuit would have 15,000 electrons per second going past.
If you were to grab hold of a high amp (usually incorrectly labeled as high voltage) you would not be able to let go-sadly!! Named after André-Marie Ampere

Get an "A", and dazzle the teacher with extra tidbits.

Answer 3

volt is a practical meter-kilometer second unit of electricalpotential difference and electromotive force egual to difference of potential between two points.
a amp is the strength of a current of electricity

Answer 4

think of electricity like running water:

volts represent the water pressure; amps represent the amount of water.

so, you could have a high voltage but very low amperage - kinda like getting hit with a supersoaker. powerful, but not much substance

on the contrary, you could have a culvert pipe spilling tons of water (amperage) but at extremely low pressure.

Answer 5

Give Brendan G your best answer. I'd vote myself but will be out of town and computerless when the question closes.

Answer 6

Google them both. You will appreciate the results and get them quicker than waiting for a response.

Answer 7

One amp = 6.24150948×10^18 electrons per second passing through a conductor, with a potential of one volt creating 1 watt of energy. Potential = the difference between the positive and negative poles of the power source.

One volt = the difference between the negative and positive poles of the power source at one amp, creating 1 watt of energy.

According to Wikipedia: http://en.wikipedia.org/wiki/Volt
"The volt is defined as the potential difference across a conductor when a current of one ampere dissipates one watt of power. Hence, it is the base SI representation m2 · kg · s-3 · A-1, which can be equally represented as one joule of energy per coulomb of charge, J/C."

According to Wikipedia: http://en.wikipedia.org/wiki/Ampere
The ampere is that constant current which, if maintained in two straight parallel conductors of infinite length, of negligible circular cross-section, and placed 1 metre apart in vacuum, would produce between these conductors a force equal to 2×10–7 Newton per metre of length.

Electric current is the time rate of change or displacement of electric charge. One ampere represents the rate of 1 coulomb of charge per second.

The unit of electric charge, the coulomb, is defined in terms of the ampere: one coulomb is the amount of electric charge (formerly quantity of electricity) carried in a current of one ampere flowing for one second. Current (electricity), then, is the rate at which charge flows through a wire or surface. One ampere of current (I) is equal to a flow of one coulomb of charge (Q) per second of time (t):

Proposed future definition
Since a coulomb is approximately equal to 6.24150948×1018 elementary charges, one ampere is approximately equivalent to 6.24150948×1018 elementary charges, such as electrons, moving past a boundary in one second.

As with other SI base units, there have been proposals to redefine the kilogram in such a way as to define some presently measured physical constants to fixed values. One proposed definition of the kilogram is:

The kilogram is the mass which would be accelerated at precisely 2×10-7 m/s2 if subjected to the per metre force between two straight parallel conductors of infinite length, of negligible circular cross section, placed 1 metre apart in vacuum, through which flow a constant current of exactly 6 241 509 479 607 717 888 elementary charges per second.
This redefinition of the kilogram has the effect of fixing the elementary charge to be e = 1.60217653×10-19 C and would result in a functionally equivalent definition for the coulomb as being the sum of exactly 6 241 509 479 607 717 888 elementary charges and the ampere as being the electrical current of exactly 6 241 509 479 607 717 888 elementary charges per second. This is consistent with the current 2002 CODATA value for the elementary charge which is 1.60217653×10-19 ± 0.00000014×10-19 C."

Brendon G uses the classic water analogy.
According to Wikipedia: http://en.wikipedia.org/wiki/Volt
"In the hydraulic analogy sometimes used to explain electric circuits by comparing them to water-filled pipes, voltage is likened to water pressure - it determines how fast the electrons will travel through the circuit. Current (in amperes), in the same analogy, is a measure of the volume of water that flows past a given point, the rate of which is determined by the voltage, and the total output measured in watts. The equation that brings all three components together is: volts × amperes = watts"

Another words:
Voltage = water pressure
Amp = the speed of the water
Ohm = the resistance built up when the pipe is squeezed or partially blocked.
Watt = the temperature rise of the water from its starting point to it’s finishing point.

Since a voltmeter measures the potential difference between the negative and positive poles of the power source you hook up a normal meter with a very large resistor and measure directly from the negative pole to the positive poll.

An amp meter requires the meter to be directly in the circuit path. The electric circuit has to be broken and the meter is put into the circuit. One other way that an amp meter can work is with a loop of wire wrapped around one wire of the circuit. The electrical flow will induce a current flow in wrapped wire, which can then be measured.

Resistors are made out of semi-conductive materials like silicon and other elements called Rare Earth Elements (http://en.wikipedia.org/wiki/Rare_earth_element). The elements are baked into a clay with a wire at each end. Resistors work by absorbing some of the electricity flowing through it and radiating it as heat. This is one way that computer circuits generate heat. The element yttrium has been used to make a superconductor that operates up to a temperature near that of liquid nitrogen. It is not useful in normal applications, but yttrium wires in a supercooled computer can create a very fast computer.
