Direct current (DC) never changes its direction of flow,
so it has no frequency.
because it have no freqency
the role of transforemers is to step down the ac voltage to desire value to be converted in dc
Its 1 divided by time: 1/t
The pich of a sound is the perception of its freqency.
freqency distribution
Gets higher
central freqency of narrow band pass filter is the measure of difference between upper and lower cut off freqency
For security reasons unable to provide.
there is no difference.
One of the role of the armature in the DC motor is to carry the current that is crossing the field. By carrying the current crossing the field, it creates the shaft torque in the rotating machine.
its because the higher the freqency the lower the pitch
Number of poles and supply freqency determines speed of synchronous motor. For speed control of such motors Variable Freqency Drives(VFD) are used.
