When the angle between two vectors is equal to zero?
When the angle between two vectors is zero ... i.e. the vectors are parallel ... their sum is a vector in thesame direction, and with magnitude equal to the sum of the magnitudes of the two original vectors.
What is the angle in which the dot product of two non zero vectors is equal?
It depends on what the dot product is meant to be equal to.
What are the two conditions that will show an expression considered as an absolute value?
You must look at the condition when the expression is greater or equal to zero and the case (condition) when it is less that zero.
What does a zero angle look like?
A zero angle is a straight positive line. The x coordinate is positive and y is zero. In addition, zero angle is a coterminal of 360 degree angle meaning that they lie in the same position.zero angle.------------------>An angle whose measure is 0 degrees is called zero angle.
What are the seven classification of angles according to measure?
Let a be the angle. 1. Zero: a = 0 (angle is equal to zero degrees) 2. Acute: 0 < a < 90 (the angle is between 0 and 90 degrees) 3. Right: a = 90 (the angle is 90 degrees) 4. Obtuse: 90< a < 180 (The angle is between 90 and 180 degrees) 5. Straight: a = 180 (the angle is a straight line it is equal to 180 degrees) 6. Reflex: 180 < a < 360 ( the angle is between 180 and 360 degrees) 7. Full (revolution): a = 360 (The angle is equal to 360 degrees a full circle.)
Why phase angle is zero when voltage and current are in phase?
1 & 3
What is the phase angle at unity power factor?
Zero degrees.
What are you conclusions about the phase relationship between the driver and the oscillator below and above resonance?
For small frequency of forced oscillation , the phase angle between the forced oscillator and driver is nearly zero . As the driving frequency increases the phase angle increases and is equal is PI/2 ,when both the frequencies (frequency of force and frequency of system for oscillation) are equal. For very large frequency of driver , they are out of phase.
What is phase angle of a resonant circuits?
The current through a resonant circuit is (in general) out of phase with the voltage. One measure of the phase angle is this angle. At resonance the phase angel is near zero so it can be used as a parameter to drive a self-tuning mechanism.
Why is it necessary for the angle of refraction to be equal to the angle of incidence when the angle of incidence is zero?
when the angle of refraction is zero you still need an angle of incidence because it still reflects back.
What is the phase angle between voltage and current in a purely resistive circuit?
The phase angle between voltage and current in a purely resistive circuit is zero. Voltage and current are in phase with each other.
How can you have a ground fault protection in a 3 phase 3W system?
3 phase ground fault detection on a 3 phase system requires that the vector summation of all three phase currents be measured. The vector sum of these currents should equal zero, or nearly zero for a balanced system. If a ground fault exists, then the vector sum will not equal zero. This condition must be validated using i2t techniques in order to eliminate false trips.
What is the phase angle difference between inductive load and resistive load?
The phase angle is defined as the angle by which the load current leads or lags the supply voltage.For a purely-resistive load, the phase angle is zero, because the load current is in phase with the supply voltage.For a purely-inductive load, the phase angle is 90 degrees lagging.But few loads are either purely-resistive or purely-inductive; typically, most loads are resistive-inductive. This means that, typically, the phase angle lies somewhere between zero and 90 degrees.
Explain quadrature null effect of coherent detector?
zero demodulated signal, which occurs for phase angle equal to + or - 90degrees, represent Quadrature Null Effect of the coherent detector.
What is phase angle?
The angle by which a circuit's current leads or lags its supply voltage.
Why power factor in cos phi why not in sin phi?
Because it has to be 1 when the phase angle is zero.
What is the power factor when the current and voltage are in phase?
The power factor of a load is the cosine of the angle by which the load current lags or leads the supply voltage. So if they are in phase (phase angle is zero), then the power factor must be unity (1).
