  • A battery (or transformer secondary) has two terminals - neither is “ground”, and electricity will flow between them if a circuit is formed.

    Often, one terminal of a battery or transformer is connected to a ground stake, so it’s possible for ground to become part of the circuit. But ground is not any kind of natural destination for electricity. (Other than lightning, which is a result of a charge forming between the earth and the clouds)

    it doesn’t “find” the path of least resistance. It takes (flows along) all possible paths simultaneously. If you connect two wires in parallel between the terminals of a battery, one of which is thick (resistance) and one of which is thin (high resistance), current will flow along both.











  • That’s true only for very simple situations.

    Everything from upgrading your doors and windows or your air conditioner and getting a tax credit, to renting out a room and deducting that portion of your home expenses, to working a side handyman or cleaning gig, to spending some cold-wallet crypto to buy gold, to the cost basis of previously unreported gains, to getting married and deciding to file together - the IRS doesn’t know.

    And some things are arbitrary, and you have to make the choice and then tell them what choice you made, and how you value it.
