Webb16 maj 2024 · In the circuit shown, R1 = 4Ω , R2 = R3 = 15Ω, R4 = 30Ω and E = 10 V. Calculate the equivalent resistance of the circuit asked Aug 23, 2024 in Physics by Aishwarya01 ( 32.0k points) current electricity 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:

Webb24 nov. 2024 · When resistors are connected in series, what happens? A. The effective resistance is decreased B. Nothing C. The tolerance is decreased D. The effective resistance is increased View Answer: 307. A 33 kilo ohms resistor is connected in series with a parallel combination made up of a 56 kilo ohm resistor and a 7.8 kilo ohm resistor. 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.
WebbC. completes two cycles for each complete cycle of current or voltage. D. will only have a negative value if the voltage and current are positive. 4. The power consumed by a purely resistive AC circuit can be determined using the following formula: P = Vrms x Irms. In the formula, the symbol ‘P’ stands for the: A. WebbIf Power factor = Cos θ = 1, it means that _____________. Input = Output P IN = P OUT The circuit is resistive only The angle (θ) between Voltage and Current is Zero. Show Explanatory Answer 15.

Webb11 apr. 2024 · The relationship between Power and Resistance can be expressed in two following ways: 1. P = V 2 R Where, P is the Power and we measure it in watts or W. R is the resistance measured in ohms (Ω). V = the potential difference applied across the ends of the conductor and is measured in Volts or simply V. 2.
WebbWe will first find the equivalent resistance in this branch, and then use P = V 2 / R P = V 2 / R to find the power dissipated in the branch. Solution The equivalent resistance is R middle = R 3 + R 5 = 30 Ω + 30 Ω = 60 Ω R middle = R 3 + R 5 = 30 Ω + 30 Ω = 60 Ω .
