How Do You Calculate Net Resistance in a Circuit?

Click For Summary
SUMMARY

The discussion focuses on calculating net resistance in a circuit where each resistor is valued at 3.3 kOhms. Participants emphasize using the formulas for series and parallel resistances: for series, the total resistance is the sum of individual resistances (R = R1 + R2 + R3...), and for parallel, the total resistance is the reciprocal of the sum of the reciprocals of individual resistances (1/R = 1/R1 + 1/R2...). The approach involves simplifying the circuit by combining resistors step-by-step until the net resistance is determined.

PREREQUISITES
  • Understanding of series and parallel resistor configurations
  • Familiarity with Ohm's Law
  • Basic circuit diagram interpretation skills
  • Knowledge of equivalent resistance calculations
NEXT STEPS
  • Study the concept of equivalent resistance in series and parallel circuits
  • Learn how to redraw circuit diagrams after combining resistors
  • Explore practical applications of net resistance in real-world circuits
  • Investigate the effects of short circuits on overall circuit resistance
USEFUL FOR

Students studying electrical engineering, hobbyists building circuits, and anyone seeking to understand resistance calculations in electrical circuits.

Homework Statement


Find the net resistance in the circuit. each resistance is 3.3 kOhms. see attached
Thanks!

Homework Equations


series r=r1+r2+r3...
parallel 1/r=1/r1+1/r2...

The Attempt at a Solution


I tried taking into account the short circuit and just adding two. Also tried resistance of 2 in parallel and 4 in series.

Welcome to Physics Forums. :smile:

To start, can you find 2 resistors that are either in series or in parallel? Replace those 2 resistors with a single, equivalent resistor and redraw the circuit.
