Circuit diagram is a representative figure to show how the connections are put up in a circuit. This enables to understand what the components of a circuit are and therefore any changes can be made epending on the requirements.
Ohms law states that electric current is proportional to voltage and inversely proportional to resistance. This is how it is related to resistance. The unit of resistance is
| kg⋅m2⋅s−3⋅A−2 |
which is written as Ω.
