Pick the ○ next to the value you want to find, fill in the others, and it solves as you type.
What each letter means
| Quantity | Unit |
|---|---|
| Energy | J |
| Voltage | V |
| Current | A |
| Time | s |
Worked example
Find the energy when Voltage = 6 V, Current = 0.5 A, Time = 60 s.
Using E = Pt = VIt: Energy = 180 J.
Frequently asked questions
What is the formula for Energy transferred?
E = Pt = VIt.
What do the letters stand for, and what units are used?
Energy in J, Voltage in V, Current in A, Time in s.
How do you calculate energy?
Put the values into E = Pt = VIt. For example, with Voltage = 6 V, Current = 0.5 A, Time = 60 s, energy = 180 J.
Can I solve for a different value?
Yes. In the calculator above, pick the circle next to any value (energy, voltage, current, time) and fill in the others: it rearranges the formula for you.
