Frequency is a scalar quantity,now comes the question how to decide which one is scalar and which one is vector,scalar quantities are those which. @Ben Crowell : I guess one can say that electric potential is a scalar under the rotation group and a component of a 4-vector under the Lorentz group. ... Is current a vector or a scalar? If someone ask you whether current and voltage are vector or scalar quantity the obviously you will answer that they are scalar quantity. ... accurate explanation for why Potential difference is a scalar, ... quantity and that is the voltage. ... because a $1$-dimensional vector is a scalar. Scalar Vs Vector Control. Using v/f control, also called "volts per hertz" control or scalar control, a drive essentially acts as a power supply of a selected frequency and proportional voltage. It is not either scalar or a vector ... Scalar Control ... flux and torque are components of frequency and voltage respectively. Using v/f control, also called "volts per hertz" control or scalar control, a drive essentially acts as a power supply of a selected frequency and proportional voltage. Why is this? Share this post. A scalar function maps something to a scalar; a vector function maps something to a vector. In DC(direct current) circuits, voltage is scalar. A Scalar Resonant-Filter-Bank-Based Output-Voltage Control Method and a Scalar ... relation between the space vector approach and scalar approach The quantity is either a vector or a scalar. . If we look closer, it is number of waves emitted per second. Is electricity a Scalar or a Vector? ... voltage is a scalar. 9. Best Answer: Voltage is scalar. It has dimensions of (per time) called as frequency. Physics stack vector or scalar sum? A secondary school revision resource for OCR Gateway GCSE Triple Science about Physics: Vectors and equations of motion. Why is current a scalar quantity? It has magnitude but not direction. However, my professor tells me that resistance is a scalar quantity. Scalars are also "vectors" in a one dimensional "vector space". Scalar and vector quantities are two types of measurement tools. akhmeteli Aug 24 '13 at 10:37 +1 for enlightening me, but this is just going to confuse the asker. Definition of vector: Vector is that quantities, which magnitude or value is change with direction with respect to(wrt) a coordinate. But in the case of alternating-current(AC) voltage is vector quantity. Well, our professor in class posed a question to all of us: Is frequency a scalar quantity? It is not either scalar or a vector ... accurate explanation for why Potential difference is a scalar, ... quantity and that is the voltage. Looking for examples of vector and scalar quantity in physics? But the thing is, a vector always obey the law of addition of vectors. Looking for examples of vector and scalar quantity in physics? Why isn't Resistance a Vector? Is current a scalar, vector or a constrained ... it is not a case of scalar multiplication of the vectors but multiplication of vector by a simple scalar area. Get expert answers to your questions in Current and Vector Design and more on ResearchGate, the professional network for scientists. Explain your answer.? The Physics Classroom Physics Tutorial 1-D Kinematics Scalars and Vectors. Using v/f control, also called "volts per hertz" control or scalar control, a drive essentially acts as a power supply of a selected frequency and proportional voltage. It may seem that current is a vector because it have a magnitude and a direction. It is because in an AC circuit the current is changing the Explain your answer.? Scalar and vector quantities are two types of measurement tools. Why potential difference is not a vector. up vote 17 down vote favorite. Now in v(t) = V(peak) sin ( t + ) the value is change w.r.t time not the polarity or direction of electric field so voltage as well as the current & inductance are scalar or time dependent scalar. Is electricity a Scalar or a Vector?
