Burn out resistor
Web10V to 3.3V through a 10 ohm resistor is still 670 mA which is enough to burn out any microprocessor. You'll need a little more than 10Ω, try 10kΩ then you would get 6.7mA which would probably be acceptable in most applications. WebActually, we first need to find the resistance of each bulb, then find the equivalent resistance of all the resistors, THEN we find the current flowing through the entire circuit. Because, sometimes the resistances can be in a parallel resistor setup, and then the current of the circuit will differ from the current of the each resistor.

WebNov 11, 2024 · It is pretty useful information to know if a resistor will burn out just by the amount of voltage present within a circuit. Using the information from How to Determine Wattage you can calculate the maximum voltage rating for any resistor. The first value to determine is the maximum current: P_{Rating}=I_{Max}^{2}*R_{Nominal} Resistors … WebOct 27, 2024 · On a 12 volt tractor if the coil plus any ballast used doesn't have around 3 ohms total resistance the coil will overheat and the points burn prematurely. Of course extreme high charging voltage can also cause overheating as can leaving the ignition on when not running
WebThe derating curve means that if you run in a 70C ambient temperature (air around the resistor) you can use 100% of the rates power (5W) but if you’re in a 155C ambient, you can only expect 50% (2.5W) before burning out the resistor. Your resistor will be able to melt solder before it burns itself up. I wouldn’t worry about it getting too hot.
WebJun 24, 2013 · A burnt out resistor can only be read one of two ways. The first is the color code on the resistor, if it is through hole, or the number code if it is a smd resistor with a a number code.
