1. Calculate the total resistance for the three resistors in parallel |
|
The usual formula is seen opposite although it is easier to break down the calculation into two separate ones. These are similar to calculations you have attempted earlier. |
|
| To make the calculation easier calculate the total of the first two resistors. |  |

|
|
|
Then, take the total of the first two resistors and perform the same calculation with the third resistor. This gives the overall total resistance. |
