Paano Kalkulahin si Electrical Power
Ano ang Electrical Power?
Electrical power is the rate at which electrical energy is transferred or converted. The three equivalent power formulas (P = VI, P = I²R, P = V²/R) allow power to be calculated from any two of the three fundamental quantities (V, I, R). Power is measured in watts (W), where 1 watt = 1 joule per second.
Pormula
- P
- watts × seconds) — watts × seconds)
- V
- voltage × current) — voltage × current)
- I
- voltage × current) — voltage × current)
Step-by-Step na Gabay
- 1P = V × I (power = voltage × current)
- 2P = I² × R (useful when voltage is unknown)
- 3P = V² / R (useful when current is unknown)
- 4Energy consumed: E = P × t (joules = watts × seconds)
- 5kWh (unit on electricity bills) = kilowatts × hours
