Splet27. dec. 2024 · The resistance of a long wire is greater than the resistance of a short wire because electrons collide with more ions as they pass through. The relationship between … SpletIn circuit analysis, a short circuit is defined as a connection between two nodes that forces them to be at the same voltage. In an 'ideal' short circuit, this means there is no resistance and thus no voltage drop across the connection. In real circuits, the result is a connection with almost no resistance. recert wa test volumes

SpletThe resistance of a long wire is greater than the resistance of a short wire because electrons collide with more ions as they pass through. Resistance and wire length are directly... Splet21. maj 2024 · A wire with high resistance can be in the 5000 ohms per foot range for especially high-output ignition systems, whereas a low resistance performance wire could easily get double digit ohms per foot. Lower resistance means more of the ignition coils energy is going towards bridging the gap or the spark plug. Splet3. Which wire will heat up more and which will stay cool? 4.

Which wire has more resistance short or long?

SpletThe resistance is directly proportional to the length and inversely proportional to the area of the cross-section of the conductor. ( a ) A long piece of nichrome wire has more resistance ( b ) A thin piece of nichrome wire will have higher resistance. Splet18. feb. 2024 · Factors affecting Resistance The factors that affect the electrical resistance of a conductor are– Length of Conductor Electrical resistance (R) is directly proportional to the length of a conductor. A longer wire will have … unleashed bristolSpletA wire’s electrical resistance depends on its length and thickness. Longer wires provide greater resistance than shorter wires. Given two wires of the same length, the thicker wire would have smaller resistance than the thinner wire. (e.g., At 25° C, AWG 4 wire has a resistance of . Do hot or cold wires have more resistance? unleashed bull

SpletThe reason due to this is that a thicker wire has more space around the atoms to allow electrons to pass. But in a thinner wire it will be the complete opposite. This is for a Thick … Splet08. maj 2024 · What causes high resistance in a wire? The moving electrons can collide with the ions in the metal. This makes it more difficult for the current to flow, and causes …

SpletFor example, when the length of the wire is 20 cm, the resistance is 3.14 ohms; when the length of the wire is 40 cm, the resistance is 6.18 ohms, which is roughly double. In my main investigation, I will see if this observation applies to my results. SpletAnswer (1 of 2): “… for a given material, the resistance is proportional to the length; for example, a long copper wire has higher resistance than an otherwise-identical short …

Resistance wire … Splet06. apr. 2024 · A short wire has less resistance whereas a long wire has more resistance. Also, a thick wire has less resistance whereas a thin wire has more resistance. Greater the magnitude of current passed through a given wire, greater will be the heat produced in it.

Splet15. okt. 2014 · He argued that you wanted the resistor to have a high resistance because P = I 2 R, so P ∝ R. But I thought back to messing around with resistors and batteries, where I remember that if I attached a much lower resistance to a battery, it would begin to heat up much faster than a bigger resistor.
