9.3 Phasor (7)
	The differences between v(t) and V: • v(t) is instantaneous or time-domain representation V is the frequency or phasor-domain representation. • v(t) is time dependent, V is not. • v(t) is always real with no complex term, V is generally complex. Note: Phasor analysis applies only when frequency is constant; when it is applied to two or more sinusoid signals only if they have the same frequency.
