Ideally does a perfect multimeter have infinite resistance when testing current and voltage?
Suppose you needed to test the voltage of your car battery, so connected the multimeter between the battery's red and black terminals. Would you like the battery to sense that you were connecting zero ohms or infinite ohms between its terminals to make this measurement?Ok so Voltage is potential difference between two points and current is flow of charge... so you would want ideally infinite resistance to test the current but maybe no resistance at all when testing voltage? Is this correct, I correct my mistake?
... and ensure the probes are not left in the current measurement jacks.
Tip: Before putting your meter away always set it to a high voltage range.
