When a series circuit containing resistance and inductive reactance is connected to a ac supply the current will?
The load current will lag the supply voltage by an angle called a 'phase angle', determined by the values of resistance and inductive reactance. The magnitude of the load current will be determined by the impedance of the circuit, which is the vector sum of the resistance and inductive reactance.

What is the formula for inductive reactance in a circuit with a capacitor inductor and a resistor in a AC circuit?
to determine the total resistance, you add them vectorilly,first find the inductive reactance of the inductor by the following formula: 2 pi F L (2x3.14 x frequency in herts x inductance in henrys) next, consider the inductive reactance and the resistance as the two sides of a right triangle and the hippotanus would be the total impedance.(this combined ''resistance'' is called impedance.) to determine the total resistance, you add them vectorilly,first find the inductive reactance of the inductor by the following formula: 2 pi F L (2x3.14 x frequency in herts x inductance in henrys) next, consider the inductive reactance and the resistance as the two sides of a right triangle and the hippotanus would be the total impedance.(this combined ''resistance'' is called impedance.)
Does reactance increase with an increase in inductance?
Inductive reactance case of ac) is equivalent to resistance (in case of dc) for inductors.So if resistance increases current decreasesas well as if inductive reactance increases current decreases
When a resistive AC circuit contains inductance the total opposition to current flow is called?
The resistance of an a.c. load is called 'resistance' (R). Resistance is not affected by frequency, only by the cross-sectional area, length, and resistivity of the conductor. Having said that, because of the skin effect, which causes an a.c. current to flow closer to the surface of the conductor, the effective cross-sectional are is reduced, so the value of a.c resistance is somewhat higher than the d.c. resistance -this difference increases with frequency.The opposition to a.c due to inductive or capacitive loads is called reactance (inductive reactance or capacitive reactance), and the overall opposition to a.c. current is the vector sum of resistance and reactance, and is called impedance. That is:(impedance)2 = (resistance)2 + (reactance)2
What does capacitive reactance oppose?
Inductive reactance.
How much resistance must be connected in series with a 250 ohms inductive reactance to produce a total ciruit impedance of 400 ohms?
To find the resistance needed in series with the 250 ohms inductive reactance to give a total impedance of 400 ohms, we use the Pythagorean theorem for the impedance triangle in series circuits. Given the inductive reactance (X) = 250 ohms, total impedance (Z) = 400 ohms, and resistance (R) = unknown, we have R² + X² = Z². Substituting the values, we get R = √(Z² - X²) = √(400² - 250²) = √(160000 - 62500) = √97500 ≈ 312.5 ohms. Therefore, approximately 312.5 ohms of resistance should be connected in series with the 250 ohms inductive reactance to achieve a total circuit impedance of 400 ohms.

Is inductive reactance directly or inversely proportional to frequency?
Inductive reactance is directly proportional to frequency. This means that as the frequency of an AC circuit increases, the inductive reactance also increases. Conversely, as the frequency decreases, the inductive reactance decreases.
What does capacitive reactance oppose?
Inductive reactance.
Why at resonance the voltage drop across inductance and the voltage drop across capacitance is greater than the source voltage?
This isn't necessarily the case. It depends upon the value of resistance (which, at resonance, determines the current), and the values of the inductive- and capacitive-reactance.At resonance, the impedance of the circuit is equal to its resistance. This is because the vector sum of resistance, inductive reactance, and capacitive reactance, is equal the the resistance. This happens because, at resonance, the inductive- and capacitive-reactance are equal but opposite. Although they still actually exist, individually.If the resistance is low in comparison to the inductive and capacitive reactance, then the large current will cause a large voltage drop across the inductive reactance and a large voltage drop across the capacitive reactance. Because these two voltage drops are equal, but act the opposite sense to each other, the net reactive voltage drop is zero.So, at (series) resonance:a. the circuit's impedance is its resistance (Z = R)b. the current is maximumc. the voltage drop across the resistive component is equal to the supply voltaged. the voltage drop across the inductive-reactance component is the product of the supply current and the inductive reactancee. the voltage drop across the capacitive-reactance component is the product of the supply current and the capacitive reactancef. the voltage drop across both inductive- and capacitive-reactance is zero.
What is difference in resistance and reactance?
Resistance is a concept used for DC. the current through a resistance is in phase with the applied voltage Reactance is used for AC the current through a inductive reactance lags the applied voltage by 90 degrees. the current through capacitive reactance leads the applied voltage by 90 degrees. the net reactance is the difference between inductive and capacitive reactance
