Amps to Watts کا حساب کیسے لگائیں
Amps to Watts کیا ہے؟
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.
فارمولا
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

اکثر پوچھے جانے والے سوالات
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.
