WebbA three-phase load is a set of three exactly similar combinations of electric components arranged in exactly the same way (in series, parallel or other). The reason to have three-phase loads is the higher power demand. For … Webb17 mars 2024 · In a DC circuit, the result of V x I gives us the power (P) in watts (W) drawn by a circuit. However, in an AC circuit, this will deviate. Because in an AC circuit, the result of V x I gives us the apparent power (S) and not the real power (P) since the current and voltage are not in phase. We can further define the PF in an AC circuit as follows:

WebbEach of the resistors in a series circuit consumes power which is dissipated in the form of heat. Since this power must come from the source, the total power must be equal to the power consumed by the circuit resistances. In a series circuit the total power is equal to the SUM of the power dissipated by the individual resistors. WebbThe total power consumed/created by a circuit equals the sum of each element's power. Recall that each element's current and voltage must obey the convention that positive …

Webb22 maj 2024 · The voltage across the resistor R2 is the output voltage and we found it to equal: v o u t = R 2 R 1 + R 2 v i n. Consequently, calculating the power for this resistor yields. P 2 = R 2 ( R 1 + R 2) 2 v i n 2. Consequently, this resistor dissipates power because P2 is positive. This result should not be surprising since we showed that the power ... WebbTweet.
