Assuming all theoretical ideal components, your series resonant
circuit
would draw infinite current and produce infinite voltage at the
junction
between L & C - you'd vaporise the whole galaxy.

So what about putting in in series with a 240V load?

It would see the load as a loss vector which would change the whole
dynamic.

Explain further. The added circuit should be a "negative resistance",
which when added to a normal resistance would app to.... zero?!


In theoretically ideal components, C has current leading voltage by 90
deg
and L has current lagging by 90.

In real world components, losses alter the vector angles with the end
result
that your series resonant circuit doesn't draw infinite current and
produce
infinite voltage.


But I wonder if it would help reduce the meter reading?


It incinerates your meter so there isn't much left to read.

You could buy all 110V appliances and use capacitor "wattless droppers".

That would put I out of phase with V and screw up the meter readings.

Each capacitor needs to be dimensioned for its load - Late hybrid TCE CTVs
used a wattless dropper for the 300mA heater chain, the capacitor was
4.3uF - you can scale that for the current draw of your appliances.
