Amp is the unit of Electric Current where as Joule is a unit of energy.
1 Amp is equal to 1 coulomb per second but 1 Joule is equal to 1 newton- metre.
A factor of 10 million. 1 joule = 10,000,000 ergs 1 erg = 0.000 000 1 joule
A watt is a rate (speed) of using energy ... 1 joule per second.
The relationship is, a watt is the product of amps x volts.
When one coulomb of charge (electrons) is lifted through a potential difference of 1 volt, it gains one joule of energy. When one coulomb of charge (like 1 Amp flowing for 1 second) drops through a potential difference of one volt, it loses one joule of energy ... which is used to generate 1 joule of heat and/or light, transmit 1 watt of radio for 1 second, run a 1-watt motor for 1 second, etc.
Potential difference is defined as follows: every coloumb of charge that passes through this difference will gain (or lose, depending on direction and signs) 1 joule of energy. This unit, joule/coloumb, is simply called the volt.
Technically, there is no difference because both are measured and calculated in the same way. The only difference is how they occur or appear in nature.
A factor of 10 million. 1 joule = 10,000,000 ergs 1 erg = 0.000 000 1 joule
An amp is the actual amp while an amp chord connects the instrument to the amp.
1 amp
10 amps
Joule and calory are two different units for energy. "Quanta" is unrelated; it's the plural of "quantum".
Not much. Keyboard amp will have a better frequency range.
The 40 amp motor probably produces double the horsepower of the 22 amp motor.
Current carrying capacity is different.
what is the diference between 12V 15A DC coil & 12V 10 amps DC coil
A watt is a rate (speed) of using energy ... 1 joule per second.
The amp for audio freq. is a AF amplifier. The RF amp is for radio freqs.
