In the case of DC, and in AC when current and voltage are in phase, a volt-ampere is the same as a watt (and therefore, a kilo-volt-ampere is the same as a kW). In the case of AC, when current and voltage are NOT in phase, power = voltage x current x power factor; the power factor is the cosine of the angle between current and voltage, and it is always less than or equal to one. In such a case, a kVA would be less than a kW.
The Q factor, or quality factor, of a coil can be measured by determining the ratio of its inductive reactance to its resistance at a specific frequency. This is typically done by applying an AC signal to the coil and measuring the voltage across it and the current flowing through it. The Q factor is calculated using the formula ( Q = \frac{X_L}{R} ), where ( X_L ) is the inductive reactance and ( R ) is the resistance. Alternatively, it can be measured using the bandwidth method, where the Q factor is derived from the resonant frequency and the bandwidth of the coil's response curve.
If line BE is the bisector of segment AC, it means that BE divides AC into two equal segments. Therefore, if AB is 7, then AC must be twice that length, making AC equal to 14.
There is no special term "ac" in math, as far as I know. However, in physics, "AC" means "alternating current".

Power factor is an AC only term, and has no meaning for DC.
AC-1This applies to all AC devices (Resistive loads) with a power factor of at least power factor of 0.95 AC-3This applies to AC Inductive loads. Like squirrel cage motors.
The answer depends on whether or not a is a factor of c.
Per factor is 1 when reactive power is zero.
because of high resistance in the load.
(a - 2b)(c - 3d)
No difference in case of DC. In case of AC Watt refers to Power which includes the factor of power factor. VA does not include power factor.
ac bridges give the value of impedances like inductance, capacitance with high accuracy. it also tells us about the quality factor .
