What is meant by combined cycle?

• A really fast motorbike

• Natural gas is used for a combustion turbine, and the hot

  exhaust superheats water to produce steam, which turns a

  steam turbine

the generator is at 90 degrees?

• The voltage is at its peak negative voltage

• The voltage is at RMS level

• The voltage is at its peak positive value

• The voltage is at zero.
