4. Consider a 60W light bulb plugged into a 120V socket, and a 100W light bulb plugged into another 120V socket Recall that a bulb's brightness is related to the amount of power (in watts) that is dissipated as heat and light. a Through which light bulb is more current passing? b. Which light bulb filament has more resistance? c. If these light bulbs were connected together in series into the same 120V outlet, which light bulb will be brighter?...

1200 C of charge flow through a section of wire in 3 mins. How much current flows through it: 6.7 A 8.0 A 400 A 0.1 A The "60W" label on a light bulb means the bulb was filled with 60W at the factory the bulb is expected to burn out after it uses up 60W no matter how you use the bulb, it will supply 60 W of power none of the other choices Each of two small spheres...

In comparing wires of identical shape and carrying the same current but made of different metals, is the drift velocity in each wire inversely proportional to the number density of charge carriers? No. The drift velocity is the same for all conductors. Yes. To have the same current from k times as many carriers, it takes k times the drift speed. No. The drift velocity is directly proportional to the number density of carriers. Yes. To have the same current...
