EEE :: Alternating Current and Voltage
-
If the rms voltage drop across a 15 k
resistor is 16 V, the peak current through the resistor is -
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
-
To produce an 800 Hz sine wave, a four-pole generator must be operated at
-
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
-
If the rms current through a 4.7 k
resistor is 4 mA, the peak voltage drop across the resistor is -
A pulse waveform has a high time of 8 ms and a pulse width of 32 ms. The duty cycle is
-
A 20 kHz pulse waveform consists of pulses that are 15
s wide. The duty cycle -
If the peak of a sine wave is 13 V, the peak-to-peak value is
