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

Save guides, add subjects and pick up where you left off with your BBC account. Using Ohm’s Law (V=ꞮR), you can calculate the expected values for voltage, current, and resistance in a circuit ...

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 ...
