To calculate the total resistance of a combination of resistors connected in series or parallel, you can use the following formulas:
Series Resistance (Rs): The total resistance of resistors connected in series is the sum of their individual resistances.
Rs = R1 + R2 + R3 + ...
Rs is the total resistance and R1, R2, R3, etc., are the individual resistances.
Parallel Resistance (Rp): The total resistance of resistors connected in parallel can be calculated using the reciprocal of the sum of the reciprocals of the individual resistances.
1/Rp = 1/R1 + 1/R2 + 1/R3 + ...
After finding the reciprocal of the sum on the right-hand side, take the reciprocal again to obtain the value of Rp. Rp = 1 / (1/R1 + 1/R2 + 1/R3 + ...) Rp is the total resistance and R1, R2, R3, etc., are the individual resistances. These formulas allow you to determine the total resistance in series and parallel resistor configurations.
