Final answer:
To calculate the equivalent resistance of resistors in a parallel circuit, use the sum of the reciprocals of each individual resistor's resistance and then take the reciprocal of that sum.
Step-by-step explanation:
The student is asking how to calculate the equivalent resistance of resistors connected in a parallel circuit. To find this, we use the formula 1/Requiv = 1/R1 + 1/R2 + … + 1/Rn, where Requiv is the equivalent resistance and R1, R2, …, Rn are the resistances of each individual resistor in the parallel circuit. Once you have calculated the reciprocal of the equivalent resistance using the formula, you take the reciprocal of that result to get the actual equivalent resistance. If there are only two resistors in parallel, the formula simplifies to Requiv = (R1 * R2) / (R1 + R2), which is more straightforward to calculate. If there are additional resistors, you continue adding the reciprocal of each resistor's resistance to the equation.
