WebMay 8, 2016 · Light bulbs, or any loads, in series will all have the same current. This is unrelated to Ohm's Law - it's Kirchhoff's Current Law and it applies if the loads are ohmic or not. Assuming your source voltage stays the same, adding bulbs in series will increase the total resistance which will decrease the total current and make all the bulbs dimmer. WebApr 26, 2024 · As electricity passes through both Bulbs A and B, the two bulbs share the 2 units of electricity equally. 2 units of electricity ÷ 2 bulbs → each bulb receives 1 unit of electricity Since the brightness of the bulb corresponds to the amount of electricity it receives, each bulb in this series circuit has a brightness of 1 unit.

WebWe have some light bulbs that run on 240v50hz AC, and are labelled 7w, they turn on and off using the wall switch and do so regardless of whether the mains power is running or not. They have a battery and manage a couple of hours on a charge. They're infuriating though because they're unlabelled chinesium and I can't identify some components to reverse … WebRecord the bulb's brightness, current and potential difference.
