![]() ![]() The drive-coil becomes a magnet and gives an impulse to the The transistor "switches on",īecomes a conductor instead of a resistor and the electrical current is able to start flowing Generates an induction voltage on the base of the transistor. When the left magnet on the tuning fork moves to the right, the phase-sensing coil Of the tuning fork is controlled by a transistorised circuit in the following way: The "Bulova Accutron" has a frequency of 360 oscillations per second (360 Hz). The history of the development of the transistor will be dealt with in the next paragraphĪbout watches with balance wheel and transistor.
