955 MSS EVALUATION SET QUESTIONS AND
ANSWERS SURE A+
✔✔What is ESD? - ✔✔ELECTROSTATIC DISCHARGE: a brief an abrupt electric
current that flows between two objects at DIFFERENT ELECTRICAL POTENTIALS
which is caused by CONTACT, or INDUCED by AN ELECTROSTATIC field.
✔✔What is a RESISTOR? - ✔✔Electronical device that RESISTS the FLOW of
ELECTRICAL CURRENT.
✔✔Symbol for: ZENNER DIODE - ✔✔x
✔✔Definition of Zener Diode: - ✔✔Voltage Regulator, typically REVERSED BIASED.
If reverse voltage of a circuit is INCREASED the zener begins to LEAK current until the
breakdown voltage is where the current INCREASES DRAMATICALLY. Zener diode
will CONDUCT to keep the voltage REGULATED.
✔✔What is LED - ✔✔Light Emitting Diode emits different colors and are made of
different semi-conductor materials, and require different energies to light them. The
FLAT side of the LED is the NEGATIVE terminal and the LONGER LEG is the
POSITIVE lead.
✔✔What is a DIODE? - ✔✔Conducts electric current very EASILY in one direction and
VERY POORLY in the other direction. Allows DC to pass. IF it is FORWARD BIASED it
CONDUCTS with a .7VDC drop across it if it is made of SILILCON. .3V if made of
GERMANIUM. Also known as a RECTIVIER because it will stop the flow of AC in one
direction, creating a PULSATING DC wave or HALF WAVE. In the SYMBOL which
looks like an ARROW, the arrow points to the NEGATIVE/
CATHODE terminal.The other terminal is POSITIVE or (ANODE) . On an actual diode a
BAND indicates the NEGATIVE/CATHODE terminal.
