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

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 ...

In these situations, we use Ohms close Ohms The unit of electrical resistance, whose symbol is Ω. Law to find an alternative power equation where more of the information is available. When ...
