How to solve for instantaneous power
WebJan 24, 2024 · Calculate the instantaneous current flow. I = d Q d t = d d t [ ( 0.001 C) sin ( 1000 / s ⋅ t)] = ( 0.001 C) ( 1000 / s) cos ( 1000 / s ⋅ t) = ( 1 A) cos ( 1000 / s ⋅ t) Answer: If we plug in a specific time within this equation, we get an instantaneous current for that time. For example, if t = 1, the current would be 0.174 A. At t = 3 s, WebHonestly, to calculate "Average Power" take instantaneous power P ( t) = V ( t) ∗ I ( t) and average it on the interval P a v e = 1 T 2 − T 1 ∫ T 1 T 2 V ( t) I ( t) d t like you did before. …

Web23. (i) Let an instantaneous voltage v be represented by v = VM sin 2π ft volts. This is a waveform which varies sinusoidally with time t, has a frequency f, and a maximum value, VM. Alternating voltages are usually assumed to have wave-shapes which are sinusoidal where only one frequency is present. WebMar 26, 2016 · In physics, you can calculate power based on force and speed. Because work equals force times distance, you can write the equation for power the following way, assuming that the force acts along the direction of travel: where s is the distance traveled. However, the object’s speed, v, is just s divided by t, so the equation breaks down to.
WebNov 6, 2015 · Instantaneous power is simply the instantaneous voltage times instantaneous current. This is true regardless of the power factor, amount of "reactive power", phase angle, or any other way of expressing this same issue.
