WebJul 9, 2024 · The capacitance of a capacitor is inversely proportional to its insulation resistance (IR), which is a measure of the capability of a material to withstand leakage of current. Since thermal energy increases the diffusion of charge carriers, leakage of current increases with temperature. Typically, the IR of most dielectrics at 125°C decreases ... WebThe unit of capacitance is the farad (F), named for Michael Faraday (1791–1867), an English scientist who contributed to the fields of electromagnetism and electrochemistry. Since capacitance is charge per unit voltage, we see that a farad is a coulomb per volt, or. size 12 {F= { {"1 C"} over {"1 V"} } } {} 19.51.
