Eye Reading. When I talk to a person, I look into their eyes.Eyes say much more than spoken words - when I look into a person's eyes, I can tell many things about their feelings and their personality.That's one of the reasons I love reading people's eyes. Have you ever just looked in someone's eyes.
How to measure dc voltage with a digital multimeter. 1. Turn dial to. Some digital multimeters (DMMs) also include. If uncertain of which to choose, start with, which handles higher voltage. 2. First insert the black probe into the COM jack. 3. Then insert the red probes into the V Ï jack. When finished, remove the probes in reverse order: red first, then black.
A voltmeter is used to measure potentials as shown in Figure 1. The voltmeter has two clips that are colored red and black. When the red clip is connected to the anode and the black clip is connected to the cathode, a positive voltage is detected as shown in Figure 1. If the clips are backwards, a negative voltage is detected. In order to practice using the voltmeter, you can measure the potential of a closed battery. Turn on the meter and if it is not set to voltage push the + button once or twice. 1) Measure the potential difference of a AA (1.5 V) battery.
