The key is to ensure that a 15amp breaker has no more than 6 220-240V wall sockets,if more than 6, the extra sockets must be serviced by a different breaker to avoid overloading the D.B
because of the inductance associated with the circuit, it takes time to establish magnetic fields around all the wires and whatnot. This requires extra current at startup.

Without knowing the amperage capacity of the circuit the question is irrelevant. 4500 Watts at 240 volts would draw about 18.75 Amps. Calculating a little extra for safety would mean that you should use a 30 amp circuit. Perhaps that's not the question you were asking.

A Hanukkah menorah, also known as a Hanukiah, has nine branches instead of the usual seven branches of a traditional menorah. The extra socket is for the Shamash, which is the servant candle used to kindle the other candles. Each night of Hanukkah, one additional candle is lit, so the Shamash is used to light the other candles without diminishing their importance.
Many of these are many for removing and replacing spark plugs in engines.
microprocessors, which in large part were developed as a means of putting more circuit functions in one chip without having to add large numbers of pins to the package to get access to the extra functions.
yes
It creates an extra load to the circuit if placed parallel to other circuits. this load approaches the equivalent of a short circuit as the resistance value placed there reduces.
