22-6 Electrical Variables
Equation 22.12. In particular, from voltage drops v
AB
and v
BC
, the load current and load voltage can be
directly derived; instead, v
AC
is used to retrieve information about their relative phase.
If currents derived by voltmeters are neglected and the current i
L
owing into the load L is assumed to
be equal to that owing into the resistor R, the statement can be demonstrated as follows:
v v Ri
