Struggling with DC Circuit Combinations?

Click For Summary
SUMMARY

The discussion centers on solving DC circuit combinations involving both series and parallel resistors. The participant is working with a 20.0 ohm resistor and a current of 3.2A, applying Ohm's Law (V=IR) and the formula for equivalent resistance (1/Req = 1/R1 + 1/R2). The use of Kirchhoff's Current Law is highlighted as a method for solving circuit problems, particularly in conjunction with symmetry to simplify calculations. The participant confirms that their answers appear correct based on the methods employed.

PREREQUISITES
  • Understanding of Ohm's Law (V=IR)
  • Knowledge of equivalent resistance calculations in series and parallel circuits
  • Familiarity with Kirchhoff's Current Law

All the answers look correct to me.
 
I agree. All correct and pretty much using the best methods.

For question c) you used Kirchhoff's Current Law. It would also be possible to use that and the symmetry of the problem to answer question g.
