Converting Coulombs to Joules Without Voltage

Click For Summary
SUMMARY

Converting coulombs to joules without knowing voltage is not feasible, as these units represent fundamentally different physical quantities. A coulomb (C) measures electric charge, while a joule (J) measures energy. The conversion requires knowledge of power (W) and current (A), as the relationship is defined by the equation Joule = Volt * Coulomb. Therefore, without voltage, the conversion cannot be accurately performed.

PREREQUISITES
  • Understanding of electrical units: Coulombs, Joules, and Volts
  • Basic knowledge of electrical power calculations
  • Familiarity with the relationship between current (Amperes) and charge (Coulombs)
  • Concept of energy measurement in physics
NEXT STEPS
  • Research the relationship between electrical power and energy
  • Learn about the conversion of energy units, such as Joules to calories
  • Study the principles of electric charge and current in circuits
  • Explore the implications of voltage in energy calculations
USEFUL FOR

Students in physics, electrical engineers, and anyone interested in understanding the relationships between electrical quantities and energy conversion.

Hi
Is it possible to convert coulomb to joule without knowing volt?

I think you're asking at the wrong forum!
Coulomb (C, AND THIS IS NOT THE SPEED OF LIGHT! :smile:) Is how many currents/Ampere travels for 1 second.
Coulomb = Ampere * Sec; Sec = Coulomb/Ampere
Joule = Watt * Sec
So
Joule = Watt * Coulomb / Ampere.
Only if you know the power (W) and the current (A)
But, then again.
Volt = Wat / Ampere, so we're back to
Joule = Volt * Coulomb

They are completely different quantities. That's like asking "is it possible to convert number of apples to meters without knowing the time of day?" - the answer is no, that does not make sense.

Ahhh, you're right! I'm trapped by this question.
Perhaps this is true?
Is it possible to convert miles to KM?
Is it possible to convert joule to erg?
Is it possible to convert Litre to cc?
Something like that?

And, before you know it, it's been moved to the correct forum.

To expand on Stephanus's post this is a nice diagram of the relationships:

Good picture. Very informative. Thanks.
And for you to know (look at mfb's answer). I reply the wrong answer to the wrong question (at the wrong forum :smile:)

Sure.

Ahh, you're the one.
Can I ask. I'm given the "First to answer" Badge. But I think my answer is wrong. I misunderstood the question. Can we have badge for wrong answer?

And I reported it. :oldbiggrin:

And we just chat each other without the OP responds to our answer??
Or perhaps the op still watches Relativity sub forum to find his post :oldlaugh:
