In this case the equivalent resistance of N identical resistors is the resistance of one resistor divided by N, the number of resistors. Here's a way to check your answer. If you have two or more resistors in parallel, look for the one with the smallest resistance. The equivalent resistance will always be between the smallest resistance divided by the number of resistors, and the smallest resistance. Here's an example.
Many circuits have a combination of series and parallel resistors.
This allows the current to be determined easily. The current flowing through each resistor can then be found by undoing the reduction process. Two resistors connected together so that the tail of one is connected to the head of the next, with no other path for the current to take along the line connecting them, are in series and can be reduced to one equivalent resistor. Finally, remember that for resistors in series, the current is the same for each resistor, and for resistors in parallel, the voltage is the same for each one.
