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

∙ 9y agoAn inductive load opposes a.c. current due to its inductive reactance (symbol: Xc), expressed in ohms. Inductive reactance is directly-proportional to the inductance (expressed in henrys) of the load and the frequency (expressed in hertz) of the supply.
The overall opposition of an resistive-inductive circuit to a.c. current is the vectorial-sum of a load's resistance and inductive reactance is termed impedance (symbol: Z), and is also expressed in ohms.

What is the change in current when frequency changes from 8 khz to 400hz?
That depends on the circuit. For a pure resistive circuit (no inductance and capacitance), the frequency will have no effect on the current.

What is inductance and capacitance and impedence?
The inductance of an inductor is the capacity of the inductor to induce electric flux. The capacitance of a capacitor is the capacity of the capacitor to store charges. THE IMPEDANCE OF A CIRCUIT IS THE TOTAL OPPOSITION OFFERED TO THE FLOW OF ELECTRIC CURRENT.
What will happen to the current or voltage if AC circuit contains both resistance and inductance?
If ther is a resistive load we got curent and voltage in phase. If the load is inductive curent lags behind the voltage. IN THIS CASE THER IS BOTH LOAD THAT MEANS CURENT WILL LAG BEHIND THE VOLTAGE
Which one of the following statements is true concerning an ac circuit that contains both resistance an inductance?
When an AC circuit contains both resistance and inductance the current and voltage will be in phase. This means having waveforms that are of the same frequency and that pass through corresponding value.

What is difference between maxwell bridge and hay bridge?
A Maxwell Bridge , also known as the Maxwell-Wien Bridge, is an AC bridge circuit used for measuring an unknown inductance by balancing the loads of its four arms, one of which contains the unknown inductance. A Hay Bridge is an AC bridge circuit used for measuring an unknown inductance by balancing the loads of its four arms, one of which contains the unknown inductance. One of the arms of a Hay Bridge has a capacitor of known characteristics, which is the principal component used for determining the unknown inductance value.
A auto transformer has what kind of induction?
self-induction."According to Lenz's law,[6]a changing electric current through a circuit that contains inductance, induces a proportional voltage, which opposes the change in current (self-inductance). The varying field in this circuit may also induce an e.m.f. in neighbouring circuits (mutual inductance)." - Wikipedia
