YOUR ANSWER : ?
When a sine wave has a frequency of 100 Hz in 12 s it goes through
YOUR ANSWER : ?
A signal with a 400 s period has a frequency of
YOUR ANSWER : ?
To produce an 800 Hz sine wave, a four-pole generator must be operated at
YOUR ANSWER : ?
The conductive loop on the rotor of a simple two-pole, single-phase generator rotates at a rate of 400 rps. The frequency of the induced output voltage is
YOUR ANSWER : ?
One sine wave has a positive-going zero crossing at 15° and another sine wave has a positive-going zero crossing at 55°. The phase angle between the two waveforms is
