Rapidly changing voltages, such as those caused by a sound or radio signal, generate greater current flows to and from the plates; then, the capacitor acts as a conductor of the alternating current. In most cases, the electrical signal is weak and must be amplified by an electronic circuit. When it is connected to a battery so that the p-type material is positive and the n-type material is negative, the electrons are repelled from the negative terminal of the battery and pass, without any obstacle, to the region p, which lacks of electrons With the battery inverted, the electrons that reach the material p can pass only with many difficulties towards the material n, which is already full of free electrons, in which case the current is almost zero. There are also many other varieties of logic circuits, including the obsolete rheostat-transistor logic and transmitter coupling logic, used for very high speed systems.
