Amps, Volts, y Watts
Understanding Electrical Units
Learn Electrical UnitsAmps, volts, y watts describe diferente aspects of electricity. Understanding su relationship helps tu choose el/la right charger, size electrical circuits, y entender tu electric bill.
El/La Three Units
Volts (V) - Electrical Presion
- Fuerza eso pushes electrons through un/una circuit
- Higher voltage = mas "push"
- US household: 120V; Europe: 230V
Amps (Un/Una) - Electrical Flow
- Amount of charge flowing per segundo
- Higher amps = mas electrons moving
- Household circuits: 15-20Un/Una
Watts (W) - Electrical Potencia
- Rate of energy usar
- Watts = Volts × Amps
- 60W bulb uses 60 joules per segundo
Key Formulas
- P = V × I (Potencia = Voltaje × Corriente)
- V = I × R (Voltaje = Corriente × Resistencia)
- P = I² × R (Potencia = Corriente² × Resistencia)
- P = V² / R (Potencia = Voltaje² / Resistencia)
Practical Ejemplos
| Device | Voltaje | Corriente | Potencia |
|---|---|---|---|
| Phone charger | 5V | 2Un/Una | 10W |
| LED bulb | 120V | 0.08Un/Una | 10W |
| Microwave | 120V | 8.3Un/Una | 1000W |
| Space heater | 120V | 12.5Un/Una | 1500W |
Conclusion
Volts medir electrical pressure, amps medir flow, y watts medir power. El/La fundamental relationship P = V × I connects them todo. Understanding estos unidades helps with everything desde charging devices efficiently un/una sizing home electrical circuits safely.
