Question

Which expression gives the vertical component of a current phasor?

Options

• \[i = v_m\sin(\omega t)\]

• \[v = v_m\sin(\omega t)\]

• \[i = i_m\sin(\omega t)\]

• \[v = i_m\sin(\omega t)\]

Answer 1

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