Did you know?
WebAug 14, 2024 · Most light bulbs don't have resistors; they are resistors. The filament introduces resistance as part of its action. The resistance is what makes it glow. Usually, if you use a resistor with... WebAs for the potential falling across the resistor but remaining constant in the wire, that too is easy to answer: it doesn't. The potential falls across the wire just like any other resistive element. Voltage remains constant across an ideal wire, but no such wire exists.
WebThe reason a light bulb glows is that electricity is forced through tungsten, which is a resistor. The energy is released as light and heat. A conductor is the opposite of a … 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 …
WebA load resistor or load equalizer helps to ensure new LED bulbs function as they should, since the OEM lights used more energy than the newly installed LEDs. Upgrading your vehicle’s lighting to LEDs requires a load equalizer, which prevents overly rapid flashing of turn signals or dashboard warning lights that say “Lamp Out”. WebExpert Answer Transcribed image text: Three identical bulbs (A, B, and C) are wired in a circuit as shown. The brightness of a light bulb is proportional to the power dissipated by the bulb. Assume that the bulbs act as ideal resistors. What happens to the brightness of Bulb B when the switch is closed?
WebOct 3, 2013 · A resistor is nothing magic. Take a long wire and measure the resistance, and you will realize that resistance is just a normal property of wires (except for superconductors). Some resistors are made up of just that. A long wire. But you can also find resistors made of other types of materials. Like this carbon film resistor:
WebIn the diagram below, assume all light bulbs act like ideal resistors. Unlike real light bulbs they have constant resistance but they give off light when current is flowing.
