Homework SourseIn the following fig Athe voltage is lagging BThe voltage is
In the following fig
A.the voltage is lagging
B.The voltage is leading
C.The voltage is in phase with current
D. None of the above
Solution
The answer is
A. the voltage is lagging.
Explanation: The curent waveform can be expressed as i=Imsin(wt)
The voltage waveform can be expressed as v=Vmsin(wt-45)
Clearly by the definitions of \'leading\' and \'lagging\', the voltage here is lagging
