introduction to alternate current

#5. The frequency of a supply is quoted in:

• ACycles or Hertz.
• BWatts.
• CMegacycles.
• DCycles / minute.

#11. A 400 Hz supply has:

• Aan output capacity of 400,000 watts.
• Ban impedance of 400 ohms.
• Ca frequency of 400 cycles per second.
• Da frequency of 400 cycles per minute.

#1. The impedance of a circuit:

• AIs the AC inductive load.
• BIs the DC inductive load.
• CIs the total resistance in an AC circuit.
• DIs the highest resistance of a rectifier.
