What happens when you stick a core into a coil inductor in an undriven circuit?

If the circuit is undriven, there is no power, so inserting a core does nothing.
In general, however, inserting a core into an inductor increases its inductance. Depending on the circuit, that lowers the resonant frequency.

How many cans on one 15 amp breaker?
Assuming the can lights is all that will be on this 15 amp 120 volt circuit and each one has no more than a 75 watt bulb installed you can install up to 19. This is determined by multiplying the amps x the voltage to get the wattage. 15 x 120 = 1800. Then multiply the 1800 x 80% and you get 1440 which places an 80% load on the circuit which is all you safely want. You then divide the 1440 by 75 which is the wattage of each bulb and you get 19.2. You could add more if you use fluorescent bulbs but someone could come along later and install incandescent bulbs and overload the circuit. So stick with no more that 19 to be safe. Remember this is a 15 amp ciruit so you must use AWG # 14 wire and not #12. If you use AWG #12 and a 20 amp breaker you can have 25 can lights with 75 watt bulbs on the circuit.
What is flux remover?
When circuit boards are assembled, the parts are soldered on. In order for the solder to make a good connection to the parts and to the board, a substance called flux is mixed into the solder. It removes oxidation and cleans up the surfaces of the different parts so that the solder can stick to them. After the board is assembled, there is still flux on the board. Flux remover dissolves the flux and washes it away.
How many electrical outlet and light can be connect to a 20 amps breaker?
In the United States and in commercial and industrial installations a 20 amp circuit may have 13 outlets, a 15 amp breaker may have 10. In a home there is no limit except common sense. I wouldn't put more than 2 rooms on a circuit. This limits how much goes off when a breaker trips, especially since in homes very often your lights and outlets share circuits.
What is the difference betweenTig wire stick welder?
a stick welder needs to replace his electrode regularly and the flux coating is on the outside while a tig machine constantly feeds the wire and the flux is produced by a filler gas
