Convert напряжение to power
| 120V @ | Ватты |
|---|---|
| 1 A | 120 W |
| 5 A | 600 W |
| 10 A | 1200 W |
| 15 A | 1800 W |
Напряжение (вольты) and power (ватты) measure different electrical properties. To convert between them, you need either current (амперы) or resistance (омы).
If you know the current, use P = V × I. A 120V circuit drawing 10 амперы provides 1200 ватты of power.
If you know the resistance, use P = V²/R. A 120V supply across a 10Ω resistor produces 1440 ватты.
You need either current (амперы) or resistance (омы). With current: Ватты = Вольты × Амперы. With resistance: Ватты = Вольты² ÷ омы. You cannot convert вольты to ватты directly.
Нет. Вольты measure electrical potential (pressure), while ватты measure power (rate of energy use). They're related through current or resistance. A 120V outlet could power anything from 0 to 1800+ ватты depending on the load.
It depends on the current draw. 120V at 1A = 120W. At 10A = 1200W. At 15A (typical circuit max) = 1800W. The formula is: Ватты = 120 × Амперы.
Ватты = Вольты × Амперы. This is Watt's Law. Think of вольты as pressure, амперы as flow rate, and ватты as the total power being delivered. Higher напряжение or current means more power.
