The frequency determining elements may be a tuned inductance-capacitance circuit or a vibrating crystal. Coils The coils (also called inductors) consist of a coiled conductor wire. Specially designed capacitors are used to measure distances, and photocells are used to detect light . By inserting a grid, formed by a spiral metallic wire, between the cathode and the anode, and applying a negative voltage to said grid, it is possible to control the flow of electrons. This principle is used in radio receivers when selecting a specific frequency using a variable capacitor. For example, simple radio frequency oscillators are used in modern key phones to transmit data to the central telephone station when dialing a number. The integrated circuits have allowed reducing the size of the devices with the consequent decrease in the manufacturing and maintenance costs of the systems. Digital clocks, laptops and electronic games are microprocessor based systems. The syllabus includes the main theoretical concepts which are fundamental to the subject, a section on some current applications of physics, and a strong emphasis on advanced practical skills. If the grid is negative, it repels them and only a small fraction of the electrons emitted by the cathode can reach the anode.
