capacitive reactance वाक्य

X volts of AC dissipates exactly the same power as X volts of DC in a given resistance, by definition, because AC voltages in this context are specified in RMS . Furthermore, the peak value of X volts AC is 1.41 X volts, so you would get a 41 % worse shock, intermittently, from X volts AC than from X volts DC . The current due to capacitive reactance is negligible, only a few microamps ( 240 V * 2 & pi; * 50 Hz * 100 pF ).
And I think if you do the math, you'll reach the same conclusion that I did; 26 nF has a capacitive reactance of 100Kohms ( that is, approaching dry skin resistance ) at 60 Hz and it's not inconceivable that a cable might have capacitances approaching at least a few nF . And thanks to gadgets such as phase-control dimmers, power lines often have noise components at frequencies much higher than 60 Hz, reducing the amount of coupling capacitance needed to allow someone to " sense " something.
