General-Oral Questions And Answers
(References: AMT-G, Chapter 4)
1. What constitutes a capacitor? -
correct answer ✅Two conductors separated by an insulator.
2. What is the purpose of a capacitor? -
correct answer ✅Stores electrical energy in electrostatic fields.
3. Does a capacitor cause current to lead or lag voltage in an AC
Circuit? -
correct answer ✅It causes the current to lead the voltage.
4. What is the basic unit of capacitance? -
correct answer ✅The Farad.
5. Why shouldn't electrolytic capacitors be used in an AC circuit? -
correct answer ✅They are polarized, it will pass current of one
polarity and block the opposite.

General-Oral Questions And Answers
1. What is meant by inductance? -
correct answer ✅Ability to store electrical energy in
electromagnetic fields.
2. What is the basic unit of inductance? -
correct answer ✅The Henry.
3. What is an example of an inductor used in a magneto? -
correct answer ✅The Coil.
4. Does an inductor cause current to lead or lag voltage in an AC
Circuit? -
correct answer ✅It causes the current to lag behind the voltage.
5. How can you find the polarity of an electromagnet? -
correct answer ✅Hold the electromagnet in your left hand with
your fingers encircling the coil in the direction electrons flow (from
negative to positive). Your thumb will point to the north pole of the
electromagnet.
6. What is meant by impedance? -
correct answer ✅The total opposition to the flow of alternating
