Can an automotive resistor have 4 grounds
WebDec 6, 2010 · In simpler language: the voltage (V) across a resistor is the current (I) through the resistor multiplied by the resistance (R). Here’s a simple circuit diagram to illustrate this: The symbol on the left is a battery, or a source of voltage. Since this is a car, we’ll just assume it’s 12 Volts. The current (I) flows through the resistor ... WebAn example would be if a resistor returns a value of infinity. This would signal the PCM that the flow of current is open somewhere in the circuit. …

WebOct 14, 2024 · Oct 13, 2024. #5. There may be different reasons. You might choose a low value resistor so that the grounds will be separated in the layout but electrically, approximately equal. An example would be an analog ground and a digital ground on the same PCB, mechanically separate, but electrically equal. You might choose a high value … WebAnything over .3 ohms is going to cause problems. Most problems can be determined by process of elimination. Start by checking fuses—if the fuses check out, then check what the wire is controlling (e.g., light, sensor, motor). Next, check the circuit to make sure the wires are not damaged and have good continuity.

WebAug 26, 2024 · Unlike the pull-up resistor, the pull-down resistor pulls the pin to a low value instead of high value. The pull-down resistor which is connected to the ground or 0V sets the digital logic level pin to default or 0 until the switch is pressed and the logic level pin becomes high. Therefore, the small amount of current flows from the 5-V source ...
