Eye Strain. When you stare at screens all day, your eyes can get tired. Take a break with the 20/20/20 rule. Look at an object at least 20 feet away for 20 seconds every 20 minutes, says Ivan Schwab, MD, a spokesman for the American Academy of Ophthalmology.
Once you have the dial on your volt meter set to measure voltage, simply touch the black lead to the negative (-) terminal on your battery and the red lead to the positive ( ) terminal on your battery.
You can measure resistance of an electronic circuit using an ohmmeter, which is a standard feature found in most multimeters. The procedure is simple: First, you disconnect all voltage sources from the circuit; then, you touch the ohmmeterâs two probes to the ends of the circuit and read the resistance (in ohms) on the meter. Resistance is measured in units called ohms, represented by the Greek letter omega (Ï). The standard definition of one ohm is simple: Itâs the amount of resistance required to allow one ampere of current to flow when one volt of potential is applied to the circuit.
