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.
Line BE is the bisectpor of segment AC of AB 7 then AC?
If line BE is the bisector of segment AC and the length of segment AB is 7, then segment AC must be equal to 7 as well, since the bisector divides AC into two equal parts. Therefore, AC = 7.

Power factor of dc ballast is 0.8. what will be the power factor same ballast in AC?
Power factor is an AC only term, and has no meaning for DC.
What is ac1 and ac3 contactor?
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.
What is the greatest common factor of the products ab ac and bc if b is a factor of c?
The answer depends on whether or not a is a factor of c.
What is the power factor of AC generator when the reactive power is equal to zero?
Per factor is 1 when reactive power is zero.
Why ac motor has low power factor?
because of high resistance in the load.
How do you simplify the boolean expression abc' plus ab'c' plus a'bc' plus a'b'c?
To simplify the Boolean expression ( abc' + ab'c' + a'bc' + a'b'c ), you can use the consensus and absorption laws. First, factor out common terms: From ( abc' + ab'c' ), factor out ( ac' ): ( ac' (b + b') = ac' ). From ( a'bc' + a'b'c ), factor out ( a'c ): ( a'c(b + b') = a'c ). Now the expression becomes ( ac' + a'c ). This can be further simplified using the consensus theorem, but it is already in a simpler form. Thus, the simplified expression is ( ac' + a'c ).
How would you factor ac-3ad-2bc plus 6bd?
(a - 2b)(c - 3d)
What does difference between Watt and Volt ampare?
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.
What are advantages of ac bridges?
ac bridges give the value of impedances like inductance, capacitance with high accuracy. it also tells us about the quality factor .
