For mechanical engineer, in addition to the knowledge of mechanical engineering, the knowledge of electronics is indispensable
to carry out complex control of mechanical system. In this class, the fundamental concepts of electricity and electronics
are introduced that involve direct current (dc), alternating current (ac), series and parallel circuits, network analysis,
magnetism, inductance, capacitance, transformers, electronic components and so on.
Although the method of operating a machine only by using a mechanism (mechanism) is an ideal, it is impossible to realize
complicated operation only by using a mechanism. Generally it is necessary to realize a complicated motion of a machine using
air pressure, oil pressure, or electric power. In such a case, electric signal is used for signal processing from a sensor,
or for control of an actuator. That is, electric knowledge is indispensable to realize a complex operation of a machine.In
this class, the knowledge of fundamental electricity is learned and it aims at coming to be able to perform calculation of
DC circuit and AC circuit.
- Understands Kirchhoff's law in a direct-current circuit, and analyzes an electric circuit.
