Why does the brightness of a bulb not change noticeably when
This makes sense that the brightness of the bulb not affected by the length of the wire and the term (E w i r e s L w i r e s) (E_{wires} L_{wires}) (E w i res L w i res ) may be negligible; the work done by the battery goes mostly into energy dissipation in the bulb, with a small amount of energy dissipation in the thick wires.
How thick does the battery wire really need to be?
in 70 degree weather my s50 pulls right around 300A on start up. i cant remember off hand what size wire you would need to carry that much current but with some searching you should be able to find an answer. remember in cold weather you''ll use more current to start the car. and you''ll always want some level of buffer so you dont melt the insulation and …
Why does the thickness of a wire affect resistance?
$begingroup$ But after a certain point, doesn''t the wire get so thick that the electrons stop bumping into each other? For example, if you have two electrons flowing through a more that''s a mile in diameter, there obviously not going to touch. So why does it make a difference what the diameter is after it gets so big that there is virtually no chance of the electrons bouncing off …

How-to Choose Wire Sizes DIY Camper Van Electrical System
Correct! The electrical demand (in amps) will be greater on the wires from the batteries to the busbar (largely because of the inverter) than the wires from the solar panels to the charge controller which is why the battery wires are larger. 2. I have 2-175 watts solar panels and 2 …
Why is thick wire used for a battery starter circuit?
Thick wire is used for a battery starter circuit because it has less resistance, which allows more current to flow. This is important because starting a car requires a large amount of current.
Why is Thick Wire Used for the Battery Starter Circuit? (How to Do)
Wire thickness, or gauge, is a measure of how large the wire is. The larger the wire, the thicker it is. The thicker the wire, the more current it can carry without heating up and melting. That''s why thicker wires are used for high-voltage applications like power lines because they can carry more current without overheating.
problems connecting throttle wires
If that does not work then I would test the Voltage of the battery pack. The controller''s label states that the battery pack needs to be at 43 Volts or above. If the battery pack is at or under 42 Volts then the controller will not operate the motor. The battery pack Voltage test should be done with the controller on and throttle engaged.

A regular gauge reading is between 13 and 15 volts, and a reading of 12 while the battery runs indicates a problem. The cable thickness is measured using a standard American Wire Gauge (AWG) method, which …
5 Things You Need to Know About Battery Cables
Battery cables are thicker than their counterparts. They have a lower American Wire Gauge (AWG) number, meaning battery cables are thicker than other cables with a higher AWG number. The thick construction of …
What is the function of the three wires of lithium batteries?
1) If your battery does not have a protective plate, the three wires are: the red wire is the positive pole, the black wire is the negative pole, and the other color wires are the middle pole of the battery.

Why does the brightness of a bulb not change noticeably when you use longer copper wires to connect it to the battery? a. All the current is used up in the bulb, so the connecting wires don''t matter. b. Very little energy is dissipated in the thick connecting wires. c. Electric field in the connecting wires is zero, so emf = E_bulb * L_bulb. d.
