Final answer:
To check a water-activated light battery, a multi-meter should be set to the voltage setting, as it measures the electrical potential of the battery and indicates if it's charged. option 1 is correct
Step-by-step explanation:
option 1 is correct When checking a water-activated light battery, the multi-meter should be adjusted to the voltage setting. This is because you are interested in measuring the electrical potential that the battery can provide, which will tell you whether the battery is charged and functioning correctly. If the multi-meter were set to current, you might risk damaging the meter or the battery if there's an unexpected surge in current flow. Similarly, setting it to resistance isn't directly relevant for checking the battery's charge.
When checking a water-activated light battery with a multi-meter, you should adjust the setting to Voltage. Voltage is the measure of electrical potential difference, and by selecting this setting, you will be able to measure the voltage across the battery. This will allow you to determine the battery's charge level.
