Electronics is a scientific and engineering discipline that studies and applies the principles of physics to design, create, and operate devices that manipulate electrons and other charged particles.
Permits electronic service if the parties agree in writing and allows parties to revoke that agreement only with ten days written notice.
This question assesses your basic electronics skills when gauging device voltages. Highlight your specific electronics knowledge and technical skills by providing examples from your experience when assessing ideal voltage sources.
Passive components do not require external sources to operate while active components require external sources to operate.
A resistor has two terminals and opposes the current in the path of the component. Resistors create voltage drops across the terminals that depend on the density of the current flowing.
Capacitors have two terminals, like resistors, but are used for storing potential energy as electrical charge. In radio electronics, I designed capacitors to block direct current and allow alternating current to pass through the device in order to tune to specific frequencies.
An inductor works by resisting the change in electric current passing through it. It stores energy in a magnetic field as current passes through it. As with my work with passive components, many of the designs I create for electronic circuit boards in computer devices require inductors.
Because silicon is more widely available for producing electronics and because of its higher heat resistance, it is more suitable for many applications.
FETs use drain, source and gate terminals to control the voltage input and are unipolar devices that rely on majority charge carriers for directing electrical current. These terminals make it possible for me to reduce nonlinearity and limit distortion to automatically bias FET devices like phase shifters.
