it is correct. but i would prefer

typedef std::complex <double> value_type;
voltage <value_type> v (value_type (2, 3));
current <value_type> i (value_type (1, 4));
impedance <value_type> z = v / i;

my point is just that std::complex <double> is the value type and should 
replace your implicit (i know its only for convenience) double.
