955 LATEST 2026 CORE EXAM MANUAL QUESTIONS AND
ANSWERS MARKED A+
✔✔What does ELI mean? - ✔✔Voltage (E) leads Current (I) VOLTAGE WAVE:
leads current wave by 90 degrees because the inductor RESISTS CURRENT.
✔✔What does ICE mean? - ✔✔Current (I) leads Voltage(E) CAPACITIVE:
Capacitor charges up with VOLTAGE which is why the Voltage FOLLOWS the
CURRENT.
✔✔Define RMS/EFFECTIVE VOLTAGE - ✔✔...
✔✔Define IMPEDANCE - ✔✔...
✔✔What does NPN stand for? - ✔✔...
✔✔What does PNP stand for? - ✔✔...
✔✔What are the three leads on a PNP, or NPN TRANSISTOR? - ✔✔EMITTER, BASE,
AND COLLECTOR. On the symbol the Emitter is the one with the arrow, the Base is the
sideway T, and the Collector is the third leg.
✔✔What are Transistors made of? - ✔✔Germanium or Callium Arsenide.
✔✔What are the three leads of a P-Mosfet or N-Mosfet TRANSISTOR called? -
✔✔Gate, Drain, and Source.
✔✔What does MOSFET stand for? - ✔✔Metal Oxide Semiconductor Field Effect
(transistor)
✔✔ State Ohm's law - ✔✔V=IXR
R=V/I
I=V/R
✔✔If current goes down, what does resistance do? - ✔✔Reistance goes up
✔✔If Voltage is CONSTANT and Resistance goes DOWN, what must Current do? -
✔✔Current HAS to go UP!
✔✔What is the definition of a short circuit? - ✔✔Zero resistance. Circuit has high
current, and zero resistance.
✔✔What would cause Current to DECREASE in a circuit, IF Voltage remained
CONSTANT? - ✔✔INCREASSE in Resistance
