How to find total resistance in a combination circuit?
Understand the Problem
The question is asking how to calculate the total resistance in a combination circuit, which involves both series and parallel resistors. The approach to solve this will involve using Ohm's Law and the rules for combining resistances in series and parallel.
Answer
Rtotal for series: R1 + R2 + R3 + ...; For parallel: 1/Rtotal = 1/R1 + 1/R2 + 1/R3 + ...
Rtotal = sum of series resistances + reciprocal of sum of reciprocals of parallel resistances
Answer for screen readers
Rtotal = sum of series resistances + reciprocal of sum of reciprocals of parallel resistances
More Information
In a combination circuit, resistors can be mixed in series and parallel forms, and it requires step-by-step calculation for each segment.
Tips
A common mistake is not correctly identifying if resistors are in series or parallel. Double-check the circuit configuration.
