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...
4.- Find the charge in C and do the number of electrons that pass in an hour through a fixed point of the filament of a 60w bulb to which a voltage of 120V DC is applied.
4) a) What is the current in a 75 W the filament of a light bulb when you tum the light on? Electric sockets supply electricity at about 110 V b) How much charge does flow through the filament during 10.0 second? c) How many electrons pass during this time? d) What is the resistance of the filament? e) What is your monthly payment if you keep the light bulb on for 4 hours every day? The cost of each...
Q1: The amount of charge that passes through the filament of certain light bulb in 2.00 s is 1.67 C. Find the current in the bulb.
Lights are instantly turned on when flipping a switch because O electrons are already in the conductive material around the light bulb and those pass throug almost instantly the electric field turns on the light bulb and not the electrons O light bulbs all contain capacitors and can store a charge electrons move very fast through conductive material

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...
Three identical light bulbs are connected to two batteries as shown in the diagram above.To start the analysis of this circuit you must write energy conservation (loop) equations. Each equation must involve around-trip path that begins and ends at the same location. Each segment of the path should go through a wire, a bulb, or a battery(not through the air). How many valid energy conservation (loop)equations is it possible to write for this circuit?---Select---012345Which of the following equations are valid...
