With this lesson, I hope to avoid a common mistake found in electronics textbooks of either ignoring or not covering…
Most of us have experienced some form of electric ”shock,” where electricity causes our body to experience pain or trauma.…
As we’ve already learned, electricity requires a complete path (circuit) to continuously flow. This is why the shock received from…
A common phrase heard in reference to electrical safety goes something like this: ”It’s not the voltage that kills, its…
If at all possible, shut off the power to a circuit before performing any work on it. You must secure…
