"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. " - The power consumed by n equal resistance

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: WebbWell the formula for equal in resistance in parallel is one over R equivalent is going to be one over R1, which is going to be one over 44S, one over R1, plus one over R2, which is going to be one over 10.
