Increase ac frequency

WebIn contrast, in cells transfected with a scrambled negative control of siRNA, the presence of 10 μM UCL-2077 increased AC frequency from 0.21 ± 0.002 Hz to 0.72 ± 0.004 Hz (n = 7, p < 0.05). Therefore, changes in AC frequency caused by this compound are explained by its modifications on K erg channels. WebTherefore, it can be seen from above that as the frequency applied across the 220nF capacitor increases, from 1kHz to 20kHz, its reactance value, X C decreases, from approx 723Ω to just 36Ω and this is always true as capacitive reactance, X C is inversely proportional to frequency with the current passed by the capacitor for a given voltage …
