Q: Attach the multimeter leads to the ports on the bottom or side of your multimeter. Set your multimeter so the arrow points at the "ACV" or "V~" option for measuring the AC voltage. Hold the pins against the positive and negative terminals of the power source you're measuring and check the reading on the multimeter display. Write down the number so you can remember it easily. It doesn't matter which pin you hold against each terminal. Never use a multimeter if the rubber around the pins has damage or tears since you could risk electrocuting yourself. Since an AC power supply sends voltage in alternating waves, DC voltage will be lower once you convert it. Write out the formula VAC/(2) and replace VAC with the AC voltage you found with your multimeter. Use a calculator to solve your equation if you want the most precise answer. For example, if the AC power source has 120 V, then your formula would be 120/(2) = 84.85 V in a DC signal. The DC voltage you calculated is known as the theoretical voltage since that's how much the current would have if it were perfect. However, currents have a voltage drop when they're converted or connected to a device so they won't have the full amount you found. If you want to find the actual output, you'll need to check with a multimeter by holding the pins against the positive and negative terminals on the device. Voltage drop may cause electronics not to work if there are not enough volts running through it.
A: Find the AC voltage of the power source with a multimeter. Divide the AC voltage by the square root of 2 to find the DC voltage. Know that the actual DC output will be less than your calculation.

Article: The moon revolves around the Earth, and as it does, we see different angles of the moon's illuminated surface. The moon doesn't create its own light, but rather shines when it reflects the sun's light. As the moon transitions from new to full and back to new again, it goes through several phases, marked by its recognizable crescent and gibbous ("bulging") shapes, which are created by the moon's own shadow. The moon phases are: New moon Waxing crescent First quarter/Half-moon Waxing gibbous Full moon Waning Gibbous Third quarter/Half-moon Waning crescent New moon The moon travels the same path around the Earth every month, so it goes through the same monthly phases. The phases exist because from our perspective on Earth, we observe the illuminated portion of the moon differently as it makes its way around us. Remember that half the moon is always illuminated by the sun: it's our vantage point on Earth that changes and determines what phase we see. During the new moon, the moon is between the Earth and the sun, and is therefore not illuminated at all from our perspective. At this time, the moon's illuminated side completely faces the sun, and we see the side that's in full shadow. During the first quarter, we see half of the moon's illuminated side and half of the moon's shadowed side. The same is true in the third quarter, except the sides we see are reversed. When the moon appears full, we see its full illuminated half, while the side that's in complete shadow faces out into space. After the full moon, the moon continues its journey back to its original position between the Earth and the sun, which is another new moon. It takes the moon a little over 27.32 days to complete one full revolution around the Earth. However, a full lunar month (from new moon to new moon) is 29.5 days, because that's how long it takes the moon to return to its position between the sun and Earth. On the moon's journey from new moon to full moon, we see a growing portion of its illuminated half, and this is called the waxing phase (waxing means growing or increasing). As the moon then goes from full to new again, we see a diminishing portion of its illuminated half, and this is called waning, which means decreasing in strength or intensity. The moon's phases always look the same, so although the moon itself may appear in different locations and orientations in the sky, you'll always be able to identify what phase it's in if you know what to look for.
Question: What is a summary of what this article is about?
Learn the names of the phases. Learn what the phases mean. Learn why the moon waxes and wanes.

Q: Dandelions grow wild and you can easily harvest their seeds when the plant is in the seed phase. This is when the top of the plant looks like a puffball. Each of the little feathery strands has a seed attached to it, so you can collect these in a bag or other small container and take them home for planting. If you prefer to purchase dandelion seeds, then check your local garden center or look for seeds online. Wild dandelion greens may have a bitter taste, while cultivated dandelion greens will not be as bitter. Dandelions do best when they have full sunlight for a large part of the day, so choose a sunny location in your garden or plan to place potted dandelions in a sunny window. Try going out in your yard a few times throughout the day to scope out the sunniest spot. For example, you could go outside at 8 am, 12 pm, and 4 pm and note where the sun is at by placing a few rocks on the edges of where the sun is shining. If you will mainly be using dandelions for their leaves, then growing them in partial shade is a better option. This will help to reduce the bitterness of the leaves and the number of flowers it produces. The dandelion seed will need to be 6 inches (15cm) apart for flowers and 2 to 3 inches (5.1 to 7.6cm) apart for greens. Flowers will need more room than baby dandelion greens because they will have deeper roots. Measure the distance between your seeds to ensure that they will have plenty of room. Leave the seeds uncovered if you are planting indoors. You will not need to worry about the seeds getting blown out. Dandelions do best in a shallow bed. Do not plant your dandelions in an area with poor drainage or a tightly packed soil, such as clay. Use a garden fork to loosen the soil before you plant if it is tightly packed. Use a loosely packed potting soil with added compost as the growing medium. Dandelions need a lot of water to thrive, so plan to water them regularly. However, do not water them too much. Water just enough so that the soil feels moist. Check the soil by poking your finger into it once every 2 to 3 days. If the soil feels moist, then they do not need water yet. If it feels dry, then give them some water.
A:
Gather or purchase some seeds. Choose a sunny location to grow your dandelions. Sow the seeds for flowers or greens. Water the dandelions regularly.
