reason that your phone smoked was the it's design
relied on the internal
impedence (a fancy word for resistance(R) ) to limit the current. When you
Close, but although both are measuered in Ohms, impedence includes
another factor: Phase. Resistance is non reactive. That is, it does not
change with the frequency of the source voltage. Impedence is a
combination of resistance and reactance (capacitive and/or inductive),
and along with phase, can change with the frequency of the applied voltage.
