WebSep 15, 2024 · You've found the energy dissipated in some resistor in some circuit that you chose to use instead of the one that the question is asking about. Better to realize that the interpretation of the question that assumes it is asking for the energy dissipated in a resistor is suspect since you don't have the information needed to answer that question. WebStudy with Quizlet and memorize flashcards containing terms like when a flashlight is operated, what is being used up?, The equation P = V ^2/R indicates that the power dissipated in a resistor decreases if the resistance is increased whereas the equation P = (I^ 2)R implies the opposite. Is there a contradiction here?, Which draws more current, a …
WebJul 28, 2024 · 2. When charging a capacitor the energy from the battery is transferred to the capacitor. If the wires have resistance, some of this energy is lost, i.e. dissipated. If the resistance is zero, there are no losses - but there is still the energy transfer from the battery to the capacitor. Share.
