Self-Test Questions Volume 1

QuestionAnswer
Symbol for inductive reactance XL
Determined by the frequency and amount of inductance in the circuit Inductance
Total opposition to the flow of alternating current Impedance
Unit of capacitance Farad
Found by adding the individual reactance’s Total reactance in an AC circuit
Number of times each cycle occurs in a second Frequency
A complete positive and negative alternation Cycle
How do electrons travel in a circuit? From negative to positive
What is the difference in current flow between an AC circuit that contains only resistance and a DC circuit that contains only resistance? The current flow in a circuit containing resistance only is the same, regardless of whether the applied voltage is AC or DC.
In an AC circuit, when is the apparent power equal to the true power? When the circuit consists of pure resistance.
When is the true power less than the apparent power? When the current and voltage are out of phase due to reactance in the circuit.
What is the formula for power factor? Power factor = watts / volts x amps

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
