This is a common activity for all types of classes basically, you give students a battery, a bare copper wire and a small light bulb the students are asked to find out different ways to make the. A piece of thin wire has higher resistance than a piece of thicker wire with the same length, which means that it's harder for electric current to move through it if you use the same battery but replace a thick wire with a thinner one, the electric current will get smaller and a light bulb in the circuit should get dimmer. This project asks whether electricity moves better through thin or thick wire take a d-cell battery and cut a straw at the same height for each.
The thickness of a wire only matters to certain voltage, and anpei requirement, like if you have a high wattage electronics like with 250v and 50a,(which makes it 25050=12500w) you need a huge thick wire to carry it to prevent over heatingotherwise it would burn. Does electricity move better through thick wires or thin ones the purpose of this science fair project is to determine whether a thin wire or a thick wire more effectively energizes a light bulb that is connected to a battery.
Does electricity move better through thick wires or thin ones kids will conduct this classic electricity experiment for this science fair project find this pin and more on science experiments by cindy sokalick. Thicker wire consumes less power compared to thin wire here i provided an experiment details with result, you will performs it own self problem: does electricity move better through thick wires or thin ones. Just a science fair project weebly link: wwwjacko-science-fairweeblycom.
Visualize the thick wire as consisting of a set of thinner wires connected in parallel (such that the net cross section of the thick wire equals the total cross sections of the thinner wires ) connecting (passive) impedances in parallel always lowers impedance (= resistance in the dc case. This feature is not available right now please try again later. Best answer: the resistance of a wire is given by r = (rho) l / a, where a is the thickness or area of cross section of the wire it is clear from this equation that the electrical resistance is inversely proportional to the thickness as such thick wire possess lesser resistance and by ohm's law, more current flows through thick wire due to lesser resistance. The main argument is that a thick wire has ' more space ' for the electrons to move around in than a thin wire but wires are made from atoms - that's where the free electrons come from but wires are made from atoms - that's where the free electrons come from.
Is is known exactly how electrons flow through wires for example a wire is conductive, the air around it is not, and thin wires conduct worse then thick wires, would this mean that the electrons force, or flow is greatest in the centre of the wire. Step 2: reading the does electricity move better through thick wires or thin ones harvard case study: to have a complete understanding of the case, one should focus on case reading. Electricity is nothing but the flow of electrons through a material in one way, it's like a garden hose already full of water when the water turned on (pressure applied) at the faucet, the pressure travels through the hose much faster than any particular water molecule, and water begins flowing out of the far end nearly immediately.
Electricity does electricity move better through thick wires or thin ones variables independent-i can change the size of the batterydependent-i hope that my thick wire will light the bulbcontrolled-that the wires will produce lightthe size of the batteriesthe light bulb kind. My research is to determine if electricity moves better through thick wires or through thin wires for this experiment i used two size d batteries, two flashlight bulbs, one 65 inch thin steel wool piece, one 65 inch thick steel wool piece, two 2 inch pieces of straw, and some electrical tape. Current electricity is the form of electricity which makes all of our electronic gizmos possible this form of electricity exists when charges are able to constantly flow as opposed to static electricity where charges gather and remain at rest, current electricity is dynamic, charges are always on the move.
