The plates have an area of 100cm 2 , the dielectric is air, and the distance between the plates is a function of time given by d ( t ) = 1 + 0.01 sin ( 200 t ) m m A constant voltage of 200 V is applied to the sensor Determine the current through the sensor as a function of time by using the approximation 1 / ( 1 + x ) ≅ 1 − x for x < < 1 . (The argument of the sinusoid is in radians.)
