Formula for power calculation
WebAnswer- We can find out the power which we require from the battery by applying the electric power formula. Thus, we will have: P = VI P = (12.0 V) (0.9 A) P = (12.0 J/C) (0.9 C/s) P = 10.8 J/s P = 10.8 W Therefore, the power which the battery requires of the mobile phone is 10.8 W. WebApr 11, 2024 · Real Power. Real Power is the power consumed by the resistive loads in an AC circuit. It can be calculated using the following formula: P (W) = V (Volts) × I (Amperes) × cos (θ) Where θ is the phase angle between voltage and current waveforms.
