Self-Test 1 Q&A 3-5
Self-Test Questions Volume 1
| Question | Answer |
|---|---|
| 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 |
