what is the different between ohm, ampere and watts?

Question

and volts. sorry miss out.

ok now i know what it means but can someone emphasise more on it? show example?

all i want to say is thank you all very much for the explanation but i want to tell you all is that i think maia's explanation gives me the clearest picture.

god help me understand more please!

Answer 1

The ampere is the unit of electricity, it is the number of electrons passing a given point per second. The volt is the unit of charge, it is like the pressure on the electrons. The ohm is the unit of resistance, it is a measurement of the force acting against the electricity. Amps times volts equals power, which is measured in watts.

Answer 2

Ohm is the standard unit of electricity/ resistance (R)

ampere is the standard unit of measurement for the strength of an electrical Current (I)

watts is the standard measure of electrical power (P)

volt is the standard unit used to measure how strongly an electrical current is sent around an electrical system (potential).

P = I*V

Answer 3

All are related to electricity. The ohm (symbol: Ω) is the SI unit of electrical impedance or, in the direct current case, electrical resistance. The ampere (symbol: A) is the SI base unit of electric current. It is named after André-Marie Ampère, one of the main discoverers of electromagnetism.

The watt (symbol: W) is the SI derived unit of power. A household lightbulb typically uses 100 watts. The Hoover Dam produces about two billion watts.The volt (symbol: V) is the SI derived unit of electric potential difference or electromotive force . It is named in honor of the Italian physicist Alessandro Volta (1745–1827), who invented the voltaic pile, the first chemical battery.

Answer 4

Volts is the amount of electrical pressure or the force that is pushing the amps through a conductor.

Amps is the actual current that is actually going down the wire and it hurts if you touch it.

Ohms are the the amount of electrical resistance or impedence to current flow.

Watts are a measure of electrical power. There are 746 watts in a horsepower.

Answer 5

ohm is the unit of resistance, ampere is the unit of current and watt is the unit of power. We're talking here about basic electricity.

Answer 6

Ohms measure electrical resistance, R.
Amperes measure electrical current, I.
Watts measure power, P.
The quantities are related by the equation P=I^2 x R ( I squared R ).

Watts are not just used to measure electrical power, but power of any kind: mechanical, optical, radio, hydraulic, etc.

Answer 7

ohm is the unit for resistivity, ampere is the unit for current, watts is the unit of power and volts is the unit for voltage also known as jouls per coulomb

Answer 8

They relate, but are not the same.

Ohms are a reference to resistance developed over a circuit
Volts are measures of the electrical levels
Amperes are current, how much energy is being developed through a circuit.

Thing is.. you have to have all three for electricity to run right.

Watts are a reference of heat displaced by energy

Answer 9

these are the units for electric resistance, electric current and electric power respectively. And the unit of electrical voltage (electric potential difference) is volts.

Answer 10

an ohm is a measure of resistance (R)
an ampere is a measure of current flow (I)
and watts is a measure of power P=IE or P=I^2R
