  • DC Circuits: Lightbulbs are Connected in Series

    13233 DC Circuits: Lightbulbs are Connected in Series Three 25 ohms lightbulbs and three 100.0 ohms lightbulbs are connected in series. What is the total resistance of the circuit? What is their resistance if all six are wired in parallel?

  • Kirchhoff's rule: Explain why lightbulbs produce more light when connected in series

    Therefore, higher W means smaller resistance of a lightbulb. When two lightbulbs are connected in series, only the current flows through the lightbulbs are the same. Therefore, W = I*V = I*I*R.
