All, please help me refine, restate, explain, understand, expand, add, remove, answer the below statements/ questions. Thanks in advance.
1.) Voltage is considered a scalar quantity. (J/C in SI Derived Units) which is a magnitude of energy per coulomb...no direction with this example. Some may say it has polarity, but is this polarity considered a direction in physics? If not what is the difference?
2.) Voltage can also be represented as a scalar function of time as with alternating current applications, where it appears as a phasor but is not really a vector. v(t) = V(peak) sin ( ωt + θ). It is just a method for simplifying and modeling the function by describing the quantity with a phase angle and peak magnitude which behaves like a vector on a real and imaginary coordinate plane.
3.) Voltage = [(kg) x (m/s^2) x (m) x (1/A)] in SI base units. Acceleration is clearly a vector quantity component of Voltage. Why then does it not make Voltage a vector quantity too?
