Everything CCEA students need to know about calculating resistance for GCSE Physics.

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

Resistance in ohms = R So resistance is easily calculated with a simple multimeter by finding the voltage and current of a circuit and dividing the voltage by the current. This is one reason some ...

We define the properties of parallel and complex circuits. Unit 5 Segment H: Parallel and Complex Circuits We define the properties of parallel and complex circuits. We examine how to find the ...
