76. The term “integrator” is derived from a mathematical function in trigonometry.
77. In an RC series circuit VS = VC + VR.
78. When a capacitor is charging, current will flow through its dielectric.
79. In the given circuit, the voltage across the capacitor 1 ms after the switch is closed is 11.61 V.
80. The frequency response curve illustrates that as the frequency of the input increases, the voltage of the output will decrease.
81. In a series capacitive circuit the smallest capacitor will have the largest voltage drop across it.
82. Capacitance is directly proportional to the dielectric constant and the distance between its plates and inversely proportional to the area of the plates.
