Another method you can use to find the total resistance of a parallel circuit is the reciprocal method. Every number has a reciprocal. The reciprocal of a given number is one divided by the number. So, the reciprocal of 5 is 1/5. The reciprocal of 12 is 1/12.

To find the total resistance of a parallel circuit using the reciprocal method, first find the reciprocal of each resistor value (1/20, 1/40, 1/50). Then, add all the reciprocal values together after simplifying the fractions to decimals (0.095). Finally, find the reciprocal of that value to get the total resistance.

The answer for this figure is 10.53 ohms.
