Use Ohms law to relate resistance, current and voltage. In National 5 Physics calculate the resistance for combinations of resistors in series and parallel.

In 1825, Ohm announced his formula to the world in a paper entitled, “Preliminary Notice of the Law According to which Metals Conduct Contact Electricity.” Not exactly a click-bait title.

Using Ohm’s Law, take 1000 watts divided by 50 ohms = 20. The square root of that is 4.47 amperes. Divide 250 watts by the same 50 ohm antenna resistance and you get 5. The square root of that is ...

Ohm's Law. To really kick things off, we will first want to examine Ohm’s Law; in plain English, the law says that the current flow/amperage through a conductor is directly proportional to the voltage ...

Ohms Law may sound like part of a high school physics lesson, but if you’re a vaper, knowing about it is crucial to avoid your device exploding. How the formula can prevent a vape explosion ...

But he’s got this false idea in his head. You need to tackle that first. To do that, turn to Kirchoff’s Law of Parallel Circuits. This law states that electricity flows in inverse proportion to the ...
