Unsymmetrical part of the wave form

The quarter cycle

The half cycle

The whole cycle

The speed with which the alternator runs

The number of cycles generated in one minute

The number of waves passing through a point in one second

The number of electrons passing through a point in one second

The current through the resistance is more

The current through the resistance is less

voltage is impressed across a pure resistance of 3.5 ohms in parallel with a pure inductance of impedance of 3.5 ohms, A. The current through the resistance is more B. The current through the resistance is less C. Both resistance and inductance carry equal currents

None of the above

Less than unity

Unity

circuit is always A. Less than unity B. Unity C. Greater than unity
