(It’s called Ohm’s Law.) For example, if you know the voltage drop across a known value of resistance, you can work out how much current must be passing through the resistor. Let’s look at an example ...

The symbol for resistance is R, it is measured in ohms \((\Omega )\). The symbol for current is I, it is measured in amperes \((A)\).

If you know “x” and “y,” you can solve for “z.” There are many laws in physics, science and nature, and Ohm’s Law is one of ...

As free electrons flow through wires, they collide with the ions in the wire which causes the ions to vibrate more. This increased vibration of the ions increases the temperature of the wire ...

We’ve all experienced power outages of some kind, be it a breaker tripping at an inconvenient time to a storm causing a lack of separation between a tree and a power line. The impact is ...
