The φ describes the phase of the sine wave. The phase is defined as how the waveform is shifted with respect to time. It is measured in degrees. The periodic nature of the sine wave shifts by 360° it becomes the same waveform when shifted by 0°. For the above formula, the real-t...
Resistance and reactance combine in a circuit to form a single property referred to asimpedance,which you measure in ohms and symbolize with Z. The formula used to calculate impedance depends on whether you're working with a series AC circuit or parallel AC circuit. The formula for a series ...
Reactance is the property of an electrical component to oppose the change in current while impedance is the combination of resistance and reactance. There are two types of reactance: Capacitive & Inductive
In electronic circuits, it is often seen that there is an electrolytic capacitor near the power supply pins of the integrated circuit. This capacitor ...
What is a displacement transducer? What does formula unit mean? What are the units of energy? What is the definition for unit rate? What is the largest unit of length? What is the CGS unit of energy? How does a quantity differ from a unit?
What are the different types of transducers? What is a magnetic field sensor? What is geomagnetic sensor? What is the transducer in a smoke detector? What is the formula for displacement? What is a hall effect transducer? Is a speaker a transducer?
The formula for cutoff frequency (corner frequency) is where R and C are the values of Resistance and Capacitance. For a simple RC low pass filter, cut-off (3dB point) is defined as when the resistance is the same magnitude as the capacitive reactance Decibel Unit Gain is often measured ...
The impedance of the capacitor is the vector sum of the capacitive reactance and ESR of the capacitor below the resonance frequency. The impedance of the capacitor after it resonates is the vector sum of the inductive reactance and ESR of the capacitor. The figure below shows the equivalent ...
The value of such a capacitor, essentially it’s “spring constant” for the mechanically–minded, is approximated by the formula in Figure 1 when the separation distance between the plates is small relative to their area. It should be noted however, that mechanical spring constants and ...
