The resistor value is calculated to be the same as if a ordinary 5w bulb was fitted.
I do understand that . But coming from an electrical engineering view less current is always safer. It's current that kills, not voltage.
I will bear that in mind later when i am wrestling with 11,000 volts, iv'e only been a sparky for 31 years!
All that i am saying is the led's with a resistor fitted are the same resistance as a oem bulb and whos to say they aren't fused resistors? They are made to be compatible with the cars oem specifications.
31 you old ***** you should know exactly the route I'm coming from then I understand what your saying an you should understand what I'm saying.
Ps never lick a megger...
OHM SWEET OHM
Ohm's Law is the mathematical relationship between voltage, current and resistance. It is named after George Ohm, its founder. Ohm's Law states that the current in a conductor is directly proportional to the voltage across it, and inversely proprtional to its resistance. In simpler terms, the law states that more voltage will produce more current if resistance stays the same, but higher resistance will cause the current to decrease if the voltage stays the same. In our household plumbing example, we can say that Ohm's Law dictates that more water pressure will produce more output if the diameter of the pipe stays the same, but a smaller-diameter pipe will cause the output to decrease if the water pressure stays the same.
With these three basic components, we have electricity. Current is "drawn" from a power supply due to the presence of a voltage placed across a load, or resistance. For instance, a typical electrical outlet has 230 volt potential (pressure- it has the capacity to give you 230 volts), but nothing is connected. If you put some load across its terminals, like a lightbulb or steam iron, you then have a complete circuit in which electrical current can flow. As we said before, a higher resistance will yield less current than low resistance. A direct short will cause a very large flow of current, because there is no resistance. If the supply is capable of delivering enough current, it is likely that the wire will eventually heat up and melt. This is why circuit-breakers and fuses are used. They limit current flow by opening (as opposed to shorting) a circuit before current flow becomes too large-- a 15A circuit-breaker will trip when the loads connected to that circuit try to pull more than 15A of current.
Makes sense, right? Good. Ohm's Law is represented as the rate of flow of electrons, and voltage is represented as the electric charge between two points.
Ohm's Law:V = I x R, where V = Voltage, I = Current, and R = Resistance.
