| See the pages on series and parallel resistors before reading this one. |
| In the diagram
we have two sets of 10 ohms in series with 15 ohms.
These can be replaced by two 25 ohms as shown in the next diagram. |
| The two 25 ohms
are in parallel and can be replaced by 12.5 ohms.
See the next diagram. |
| The two 5 ohms
are in parallel so can be simplified to 2.5 ohms.
See the next diagram. |
| The 12.5 and the 2.5 are in series so that the equivalent resistance for the network is 15 ohms. |
