SUMMARY

The calculations for the resistor problem are confirmed as correct. The voltage across the resistor (V_R) is calculated to be 6.3 V, leading to a resistance (R) of 1.4 ohms using the formula R = V/I. Additionally, the power (P) dissipated is determined to be 28.35 W using the equation P = VI. These results align with the principles of Kirchhoff's Voltage Law (KVL) and basic electrical formulas.

PREREQUISITES
  • Understanding of Ohm's Law (R = V/I)
  • Familiarity with power calculations (P = VI)
  • Knowledge of Kirchhoff's Voltage Law (KVL)
  • Basic proficiency in electrical circuit analysis
NEXT STEPS
  • Review advanced applications of Kirchhoff's Laws in circuit analysis
  • Explore power factor calculations in AC circuits
  • Learn about series and parallel resistor combinations
  • Investigate the impact of resistor tolerances on circuit performance
USEFUL FOR

Students studying electrical engineering, educators teaching circuit analysis, and hobbyists working on electronics projects.

Homework Equations



[tex]\[R = \frac{V}{I}\][/tex]

[tex]P=VI[/tex]



The Attempt at a Solution



a) Using KVL around the loop, I got [itex]V_{R}=6.3 V[/itex].
Then I used [itex]\R = \frac{V}{I}\[/itex] and got R = 1.4 ohms.

b)I used [itex]P=VI[/itex] and got P = 28.35 W.

Are my answers correct?
