TSA: Electrical Applications Exam – Most Tested
Questions and Verified Answers 2026/2027
1. Base, Collector, and Emitter: What are the pins of a transistor called?
2. Circuit Breaḳer: A automatic switch that is similar to a fuse in purpose, but can be used multiple times.
3. Conductor: A material through which charges can easily flow.
4. Electron: A negatively charged particle found in atoms that is a carrier of electricity.
5. Fission: The process used in modern nuclear power plants.
6. Fuse: A safety device with a thin metal strip that will melt if too much current passes through a circuit.
7. Galvanometer: A device that uses an electromagnet to detect small amounts of current.
8. Grounded: Allowing charges to flow directly from the circuit into Earth in the event of a short circuit.
9. Induction: A method of charging an object by means of the electric field or another object; the objects have no direct contact.
10. Insulator: A material through which charges cannot easily flow.
11. Integrated Circuit: A circuit that has been manufactured on a chip (a tiny slice of semiconductor), which can contain
thousands of diodes, transistors, and resistors.
12. Light Emitting Diode: LED stands for this.
13. Magnet: A device that attracts any material containing iron.
14. Magnetic Declination: The angle between geographic north to which a compass needle points.
15. Magnetic Domain: A region in which the magnetic fields of all atoms are lined up in the same direction.
16. Magnetic Field: The region around a magnet where the magnetic force is exerted.
17. Magnetic Field Lines: Invisible lines that map out the magnetic field around a magnet.
18. Magnetic Force: A force produced when magnetic poles interact.
19. Magnetic Pole: The ends of a magnetic object, where the magnetic force is strongest.
20. Magnetism: The force of attraction or repulsion of magnetic materials.
21. Mechanical Energy: The energy an object has due to its movement or change in position.
22. Neutron: The small uncharged particle that is found in the nucleus of an atom.

, 23. NPN: The arrow on the emitter is pointing out on the schematic of this type transistor.
24. Nucleus: The core at the center of every atom.
25. Ohm's Law: The law that states that resistance is equal to voltage divided by current.
26. Parallel Circuit: An electric circuit with multiple paths.
27. Permanent Magnet: A magnet made of material that ḳeeps its magnetism.
28. PNP: The arrow on the emitter is pointing in on the schematic of this type transistor.
29. Power: The rate at which one form of energy is transformed into another: measured in watts.
30. Proton: A positively charged particle that is part of an atom's nucleus.
