    Basic Question concerning what Amps are?

    If the wire was a superconductor, it would be so cold that your hand would freeze to the wire and not feel anything. "Why amps? Why not the lack of resistance. " You are just trying to make things complex for the beginner. No wonder he doesn't understand anything you are saying.

    BOSCH reputable car battery manufacturer? then where are datasheets?

    Measuring high a high current is a very difficult thing to do and it depends on the temperature of the day and the equipment. No two CARBON CORES (Carbon Piles) are the same. The fact that it will start your car say 10 times in a row is sufficient to say the battery is ok.

    12 volt DC lamp flasher.

    Fig 1 is badly worded. It is only a LED flasher. You need a flip flop circuit.

    Alternative Actuator Choices?

    "My project has nothing to do with sailing," You "sailed" into Electronics Point with an enormous request, asking to lift an elephant with a 9v battery as the supply. The only things powerful enough to do the job are either a boat winch or sail winch. Door and gate actuators are only very...

    Need help using Nichrome wire for a foam cutter

    To start with, the wire is connected to an AC source and it is known that 18v AC is suitable. So no other calculations are necessary. The supply just has to be increased to 63v AC and use the same current capability as the 18v supply.

    Need help using Nichrome wire for a foam cutter

    I don't know where you get the idea that 3.5 times the current is needed. No-where in this example is 3.5 times the current needed. Look at your original reply. You go on and on with completely incorrect statements and assessments. - twisting three strands together etc. You have NEVER produced...

    Need help using Nichrome wire for a foam cutter

    We are talking about the requirements for a wire 3.5 ft long. If 18v heats up 1 ft of wire, then 18v x 3.5 will heat up 3.5ft of wire. The current delivered to 1ft of wire will be the same as for 3.5ft of wire. The current does not alter.

    Need help using Nichrome wire for a foam cutter

    "To get 3.5 times the power you need 3.5 times the current. " A little knowledge is a dangerous thing. What you are talking about does not apply in this situation. You have never produced a hot-wire cutter. I have. What you are saying is entirely incorrect. Think about the actual situation...
