Question
Some lamps are made to turn on and off when the base is touched. These use a one terminal variation of the capacitive switch circuit discussed in the practical perspective section at the begining and end of chapter 6. an exaple of this type of circuit is shown below.
a. calculte the change in the voltage V(t) when a person touches the lamp. assume all the capacitors are initially discharged
b. Sketch the physical system and indicate what each capacitor models in the system. Explain what the two capacitances used to model the person corresponds to
Explanation / Answer
THE CAPACITOR DOES NOT ALLOWS SUDDEN CHANGES IN THE VOLTAGES SO WHAT EVER THE VOLTAGE v(t) THAT REMAINS SAME WHEN THE PERSON TOUCHES THE LAMP
