3 · A. Insulation Resistance (IR) is the extent to which the dielectric material in a capacitor resists leakage current. It is the resistance of the dielectric material itself*1. IR is measured by leakage current. Knowing the leakage current and applied voltage, the insulation resistance can be calculated based on the ohm''s law.
9.2: Q Factor
Thus the (Q) is a measure of the sharpness of the bandpass frequency response. The determination of (Q) using the measurement of bandwidth together with Equation (eqref{eq:4}) is often not very precise, so another definition that uses the much more sensitive phase change at resonance is preferred when measurements are being …
