Delmar 6In an R-L parallel circuit, the value of impedance can be found if total current
and voltage are not known.
True
False - correct answer ✔True
Because the voltage and current are 90° out of phase with each other in a
pure inductive circuit, the current and voltage will be at different polarities 50%
of the time.
True
False - correct answer ✔True
