WebSo what we have calculated is that these two resistors connected in parallel can be replaced by a single resistor of eight ohm. And nothing will change. Everything in the circuit will remain the same. The current in the circuit and the voltage, everything will remain the same. So let's go ahead and do that. WebAs others mentioned, the easiest way to drop the voltage is to put resistors in series from 12V to GND and measure the voltage between the different resistors and ground. Also, keep in mind that most digital voltmeters can be used to measure resistance. So you could also try that. 4. level 2. biometric records meaningWebJan 16, 2024 · 7.
