Capacitor microphones
The capacitor mic, formerly known as the ''condenser mic'', works in a completely different way to the dynamic. Here, the diaphragm is paralleled by a ''backplate''. Together they form the plates of a capacitor. A capacitor, of any type, works by storing electrical charge. Electrical charge

Electric Fields and Capacitance | Capacitors
When the voltage across a capacitor is increased, it draws current from the rest of the circuit, acting as a power load. In this condition, the capacitor is said to be charging, because there is an increasing amount of energy …
Chapter 5 Capacitance and Dielectrics
A capacitor is a device which stores electric charge. Capacitors vary in shape and size, but the basic configuration is two conductors carrying equal but opposite charges (Figure 5.1.1). Capacitors have many important applications in electronics. Some examples
8.2: Capacitance and Capacitors
The current through a capacitor is equal to the capacitance times the rate of change of the capacitor voltage with respect to time (i.e., its slope). That is, the value of the voltage is not important, but rather how quickly the voltage is changing. ... note the direction of the current source. This will produce a negative voltage across the ...

0 parallelplate Q A C |V| d ε == ∆ (5.2.4) Note that C depends only on the geometric factors A and d.The capacitance C increases linearly with the area A since for a given potential difference ∆V, a bigger plate can hold more charge. On the other hand, C is inversely proportional to d, the distance of separation because the smaller the value of d, the …
