Question

Let n represent the number of similar resistors in a circuit. Each resistor has a resistance of r. When the resistors are connected in parallel the circuit has a total resistance of R. What would the total resistance of the circuit be if the resistors were instead connected in series?

Answer 1

If each of the n resistors has the same value, the total resistance of the circuit with the n resistors connected in series would be given by:
\[\large R(total\ series)=n \times r\]
