Amps to Watts ಅನ್ನು ಹೇಗೆ ಲೆಕ್ಕ ಹಾಕುವುದು
Amps to Watts ಎಂದರೇನು?
An amps to watts converter calculates electrical power from current and voltage. Used to determine the wattage of appliances and the capacity needed from a power source.
ಸೂತ್ರ
W (DC) = A × V; W (AC) = A × V × PF
- A
- Current (A) — Electrical current in amperes
- V
- Voltage (V) — Electrical potential in volts
- W
- Power (W) — Electrical power in watts
- PF
- Power factor ((dimensionless)) — For AC loads; typically 0.8–1.0
ಹಂತ-ಹಂತದ ಮಾರ್ಗದರ್ಶಿ
- 1Watts = Amps × Volts (DC)
- 2Watts = Amps × Volts × Power Factor (AC)
- 3Power factor for motors is typically 0.8–0.95
- 4Standard voltages: 120V US, 230V EU, 240V UK

Frequently Asked Questions
How do I calculate watts from amps?
Multiply amps by volts. In AC, also multiply by power factor. Example: 10 A × 240 V = 2,400 W.
Why does my kettle pull more amps than my TV?
The kettle uses more power (watts). At the same voltage, higher wattage means higher amps. Ohm's law: W = V × A.
What's a safe amperage for a standard outlet?
In the US, 15–20 A circuit breakers are standard, supporting 1,800–2,400 W at 120 V. In UK, 13 A plugs support 3,120 W at 240 V.
