Question

Which expression gives the vertical component of a voltage phasor?

Options

• \[i = i_m\sin(\omega t)\]

• \[v = i_m\sin(\omega t)\]

• \[i = v_m\sin(\omega t)\]

• \[v = v_m\sin(\omega t)\]

Answer 1

The vertical component of the voltage phasor gives the instantaneous voltage \[v = v_m\sin(\omega t)\]. Here, \[v_m\] is the peak voltage represented by the phasor length.
