Volts Formula:
From: | To: |
The volts formula calculates electrical potential difference (voltage) by dividing energy in joules by charge in coulombs. It's derived from the basic definition of voltage as energy per unit charge.
The calculator uses the volts formula:
Where:
Explanation: This formula shows that 1 volt equals 1 joule of energy per 1 coulomb of charge. The calculator performs this simple division with your input values.
Details: Understanding voltage is fundamental in electrical engineering and physics. It helps determine the potential energy difference in circuits and is crucial for designing and analyzing electrical systems.
Tips: Enter energy in joules and charge in coulombs. Both values must be positive numbers. The default energy value is set to 1000 J to match the calculator's title.
Q1: What is a practical example of this calculation?
A: If a battery delivers 1000 joules of energy while moving 5 coulombs of charge, the voltage would be 200V (1000J/5C).
Q2: How does this relate to battery voltage?
A: A battery's voltage indicates how much energy it can provide per unit charge. Higher voltage means more energy per coulomb.
Q3: What's the difference between volts and joules?
A: Joules measure energy, while volts measure energy per unit charge. Volts tell you how much "push" each unit of charge has.
Q4: Can I calculate joules if I know volts and coulombs?
A: Yes, simply rearrange the formula: J = V × C. Energy equals voltage multiplied by charge.
Q5: Why is 1000 joules used in the calculator title?
A: It's a common reference value that makes for practical examples, though you can enter any positive energy value.
