• Question 181:

  Inductive reactance is found by using __________.

  A. XL = 2FC

  B. XL = 2FL

  C. XL = R

  D. XL = Z

  Correct Answer: B

  The formula for finding inductive reactance has to utilize the L in inductance and the fixed constant 2 as well as taking into consideration the frequency of the power applied to the circuit.

• Question 182:

  A capacitor of 100 micro farads has a capacity of __________.

  A. 100 picofarads

  B. 10 picofarads

  C. 100,000,000 picofarads

  D. 10,000 picofarads

  Correct Answer: C

  A microfarad is 1 million picofarads. Therefore, if you wish to convert micro farads to picofarads, you have

  to multiply by 1 million.

  That means the answer is "100,000,000 picofarads" because 100 times 1 million is 100 million.

• Question 183:

  The symbol for inductance is __________.

  A. XL

  B. I

  C. L

  D. XC

  Correct Answer: C

  The symbol for inductance is L. The symbol for an inductor is a loop as in a coil of wire.
