Which resistance setting should be used on an ohm-meter when checking load resistance with black to common?

Amp
kiloOhm
mAh
Ohm

The correct answer is: Amp

The correct setting for checking load resistance on an ohm-meter is to use the "Ohm" setting. This setting is specifically designed to measure resistance in ohms, which is the unit of measurement for electrical resistance. When measuring load resistance, it is essential to have the meter on the correct scale to obtain an accurate reading. Using the ohm setting allows you to determine how much opposition the load provides to the flow of current. It is essential for troubleshooting and ensuring that components are functioning properly within an electrical system. The amp setting is used for measuring current flow in amperes, not resistance. The kiloOhm setting measures resistance in thousands of ohms, but it wouldn't be appropriate for all resistance checks if the value is much lower. The mAh setting is typically used for measuring battery capacity rather than resistance. Therefore, the appropriate choice for measuring load resistance when connecting black to common is to utilize the "Ohm" setting.
