# Parallel Resistor Values Table

It is relatively easy to calculate the overall resiatance of two resistors in parallel. Bu when wanting to make up another value it is often handy to be able to refer to a table of pre-calculated values to discover the best options.

This table provides a list of resistor values that can be created from preferred resistor values.

This can be very useful when trying to obtain an exact resistor value when the required ones are not available.

## Parallel resistor values table

The table below gives values for resistors in parallel for a variety of values in the various tolerance, E-series categories.

Column A gives the required resistor value, and column B gives the first choice combination for the parallel resistors. A second choice is shown in column C. The values should be a close tolerance as possible, typically 0.5%.

The table below provides resistor values using standard values, even if they are in a higher tolerance series, E series than might otherwise be used.
