How do you factor this equation using the ac method 4x3-19x2 plus 15x?

x(x - 1)(4x - 15)


Which is greater 1kw equals equals KVA?

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.


How do you measure Q factor of a coil?

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.


Line BE is the bisector of segment AC. If AB 7 then AC .?

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.


What is Ac in math?

There is no special term "ac" in math, as far as I know. However, in physics, "AC" means "alternating current".
