Jinsi ya kukokotoa Electric Power

Electric Power ni nini?

Electric power is the rate at which electrical energy is transferred or consumed. P = V × I (voltage × current), and by Ohm's law can also be expressed as P = I²R or P = V²/R. Measured in watts (W) or kilowatts (kW).

Mwongozo wa Hatua kwa Hatua

1. 1P = V × I (Power = Voltage × Current)
2. 2P = I² × R (using resistance and current)
3. 3P = V² / R (using resistance and voltage)
4. 4Energy consumed: kWh = kW × hours; cost = kWh × tariff rate
