Volts to joules calculator helps you swiftly convert the electric potential (volts) into energy (in joules) or vice versa. It provides an accurate way to determine the amount of energy present in an electrical system based on voltage and charge (in coulombs).
Converting one volt to joules involves a simple formula that shows the energy quantity from the electrical potential:
\( J = V \times C\)
Where:
Let's say you have a battery with a voltage of 9 volts and a charge of 5 coulombs. If you want to calculate the energy stored in the battery, use the following formula:
J = V × C
Now, put the values to the equation:
J = 9 volts × 5 coulombs
J = 45 joules
Volts to Joules Conversion Chart demonstrates the direct connection between voltage and energy in electrical systems, such as:
| Scenario | Voltage (V) | Charge (C) | Joules (J) | What it powers |
|---|---|---|---|---|
| AA battery | 1.5 | 2 | 3 | Small LED light |
| Car battery (starting) | 12 | 100 | 1200 | Engine starter motor |
| Phone charger | 5 | 1 | 5 | Phone battery |
| Lightning bolt | Millions | Billions | Trillions | Intense heat and light |
| Toaster oven | 110 | 5 | 550 | Heating element |
