Current directly proportional to voltage
WebApr 14, 2024 · ε 0 is the permittivity of vacuum. ε r is the relative permittivity of the material. A is the area of the plates. d is the distance between the plates. C is the capacitance in Farad. From this equation, we can see that the capacitance value is directly proportional to the relative permittivity of the material that is filled between the conducting plates of … WebSep 3, 2012 · The current flowing through the motor can then be calculated: I = ( V S − V e m f) / R = ( V S − k i ∗ ω) / R V S = source voltage R = motor electrical resistance Now let's consider the mechanical side of the motor. The torque generated by the motor is proportional to the amount of current flowing through the motor: τ = k t ∗ I k t = a constant
