SUMMARY

The discussion centers on calculating the power dissipated by a resistor connected to a 1.5 V battery with a resistance of 0.25 ohms. The current (I) is calculated using Ohm's Law, resulting in 6.0 A. The user initially sought assistance in determining the power dissipation but later indicated they had resolved the issue independently. The power dissipated can be calculated using the formula P = I²R, leading to a definitive understanding of power dissipation in resistive circuits.

PREREQUISITES
  • Understanding of Ohm's Law (I = V/R)
  • Knowledge of power calculation formulas (P = I²R)
  • Familiarity with basic electrical concepts (voltage, current, resistance)
  • Ability to perform basic arithmetic operations
NEXT STEPS
  • Research the application of the power formula P = I²R in different circuit configurations.
  • Learn about the implications of resistor values on power dissipation in electrical circuits.
  • Explore the relationship between voltage, current, and resistance in series and parallel circuits.
  • Investigate the thermal effects of power dissipation in resistors and their impact on circuit design.
USEFUL FOR

Students studying electrical engineering, hobbyists working on electronics projects, and anyone interested in understanding power dissipation in resistive components.

Homework Statement



Calculate the power dissipated by a resistor connected to a 1.5 V battery when R = 0.25 ohms.

Homework Equations



I = V/R

The Attempt at a Solution



I = V/R
=1.5 V/0.25 ohms
=6.0 A

So, I know the current, but I don't know how to get the power that is dissipated. Can somebody please help me?
