(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 ...

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 the most important in understanding basic electricity.

For each pair of results calculate the resistance, R using \(R = \frac{V}{I}\). Record your results in the third column of the table. Plot a graph of voltage, V on the y-axis v current, I, on the ...

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 ...
