Web1. In case of Inductive circuit, Frequency is ___________Proportional to the inductance (L) or inductive reactance (XL). 1. Directly 2. Inversely 3. No Effect Show Explanatory Answer … WebFeb 24, 2012 · The formula for inductive reactance is X L = 2πfL. So, if frequency increases, inductive reactance X L also increases and if inductive reactance increases, total impedance of circuit also increases and this leads to variation in phase angle θ with frequency. So, in series RL circuit if frequency increases,
Inductive Reactance and Capacitive Reactance - Definition, …
WebApr 7, 2024 · As described above, inductive reactance increases with the rate of change in the current direction, or the frequency of the circuit. This frequency is represented by the symbol ƒ, and is measured in Hertz (Hz). The full formula for calculating inductive reactance is XL = 2πƒL, where L is the inductance measured in Henries (H). WebSep 12, 2024 · where ω = 2πf = 120πrad / s is the angular frequency. Since v ( t) is also the voltage across each of the elements, we have v(t) = vR(t) = vC(t) = vL(t) = (10V)sin120πt. a. When R = 100Ω, the amplitude of the current through the resistor is I0 = V0 / R = 10V / 100Ω = 0.10A, so iR(t) = (0.10A)sin120πt. b. fishing pole outline
In case of Inductive circuit, Frequency is - Electrical MCQ
WebDetailed Solution for Test: Current & Voltage in an Inductive Circuit, Capacitive Circuit - Question 6. In a pure inductive circuit, current is lagging by 90 degrees from the voltage. The power factor is the cosine of the angle in between the voltage and the current. If the angle between the voltage and current is 90, then cos90=0. WebExpert Answer. 1. Capacitive reactance is given by: Xc = 1/ (w*C) w = angular frequency = 2*pi*f Xc = 1/ (2*pi*f*C) So we can see that capacitive reactance is inversely proportional to both frequency and capacitance, So Given statement is TRUE. 2. WebThe inductive reactance is found directly from the expression XL = 2πf L. Once XL has been found at each frequency, Ohm’s law as stated in the equation I = V / XL can be used to find the current at each frequency. Solution for (a) Entering the frequency and inductance into the equation XL = 2πf L gives fishing pole or fishing rod
