Can light bulbs take dc power
WebNov 26, 2024 · For this much voltage, if this was the voltage across that device, then the power across that, power dissipated would be 50 watts. But clearly, in this example, the voltage across the bulb is not 10 volts, we can see it's 5 volts. So the power dissipated in this bulb won't be 50 watt, in fact we can guess it's gonna be lower than that. WebJan 18, 2024 · This means that when a circuit running on AC has a light bulb, it doesn't have a steady flow of positively charged electrons running through it like it does on DC power, so the light is not ...
