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.

polarized, it will pass current of one polarity and block the opposite.
(References: AMT-G, Chapter 4)
1. What is meant by inductance? ✔Correct Answer-Ability to store electrical energy in
electromagnetic fields.

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
current. It is the vector sum of resistance, capacitive reactance, and inductive reactance.
