current to energy calculator
Convert electrical current (A) to energy (Wh or kWh) using 𝐸 = 𝐼×𝑉×t, where I is current, V is voltage, and t is time.
energy calculation in electrical circuits
Multiplying amperes by volts by hours has the formula to determine energy gained per current. Dividing Wh, you obtain kWh by dividing by 1000.
Formula & Table Summary:
\( E_{\text{Wh}} = I \times V \times t \)
\( E_{\text{kWh}} = \frac{I \times V \times t}{1000} \)
Where: I = current (A), V = voltage (V), t = time (hours)
current and voltage to energy
The Current to Energy Calculator will assist you in calculating the amount of electrical energy that is consumed on the basis of the current, the voltage, and the time. The quantity of energy consumed is computed in watt-hours (Wh) by multiplying the current in amperes, the voltage in volts, and the operating time in hours. This is a necessary calculation in the estimation of electricity consumption, battery sizing, or electricity consumption in electrical appliances. The Current to Energy Calculator answers the question of how to transform amps into Wh or kWh.
I = E / V / t, where I is current, V is voltage, and t is time measured in hours.
electrical energy from current
| I (A) | V (V) | t (h) | Calculation | E (kWh) |
|---|---|---|---|---|
| 2 | 230 | 3 | (2×230×3)/1000 | 1.38 |
| 5 | 120 | 2 | (5×120×2)/1000 | 1.20 |
| 10 | 240 | 1 | (10×240×1)/1000 | 2.40 |
| 3 | 110 | 5 | (3×110×5)/1000 | 1.65 |
| 8 | 230 | 0.5 | (8×230×0.5)/1000 | 0.92 |
Frequently Asked Questions - current to energy calculator:
How to convert current to energy?
Multiply current (A) by voltage (V) and time (h) to get Wh, then divide by 1000 for kWh.
What units are used for energy?
Energy is measured in watt-hours (Wh) or kilowatt-hours (kWh).
Can I use this formula for AC and DC?
Yes, but for AC you may need to include the power factor.
Why divide by 1000 for kWh?
Because 1 kWh equals 1000 Wh.
What is the role of time in the formula?
Time determines how long the current is flowing, affecting total energy.
What is the formula for energy?
