WebApr 13, 2024 · The final tip for overcoming the resistance to change is to adapt and sustain the change in your IT service delivery processes and culture. Change is not a one-time … WebWhen the bulbs are connected to a voltage source, the voltage is divided over the two bulbs in series, and the power consumed by each will be U²/4R. The bulbs in parallel each have a voltage of U over them, and therefor each consumes U²/R power. In this case the claim in the question is correct. the bulbs in parallel are brightest.
WebJul 27, 2016 · The light bulb is in series with the wires in the lamp and wall. Since the current through all elements in a series is the same (neglecting capacitance), the elements with higher resistance will dissipate more heat. You want the light bulb to heat up, not your wires in your walls (which can cause fires). It all goes back to the basics: ##P = IV##. WebJun 18, 2024 · The resistance of a lightbulb is not constant. Becomes the lightbulb resistance is not constant but will change with the applied voltage. See the graph of resistance of a \$100W/230V\$ light bulb in …
WebIf that resistance stayed the same with 120 V applied, Ohm's Law tells us that the bulb would draw about 12.5 amps and dissipate about 1,500 watts.
