Preformed vitamin A occurs naturally in dairy products, eggs, fish and meat, especially liver. Carotenoids are found in bright yellow and orange vegetables such as carrots, pumpkin and sweet potatoes, broccoli and spinach.he best food sources are beef and chicken liver, whole milk, cheese, and eggs. You get vitamin A from beta-carotene in carrots, mango, sweet potato, spinach, cantaloupe, kale, apricots, red pepper, broccoli, and fortified foods.
When the switch is first closed, the voltage across the capacitor (which we were told was fully discharged) is zero volts; thus, it first behaves as though it were a short-circuit. Over time, the capacitor voltage will rise to equal battery voltage, ending in a condition where the capacitor behaves as an open-circuit.
YOU CANNOT DISCHARGE A START CAPACITOR LIKE A RUN CAPACITOR WITH A SCREWDRIVER! Many / most of the time, the start capacitor will have a bleed resistor attached. Switch the ohmmeter to the Volts AC position. To discharge the start capacitor, use your multimeter in the volts AC mode. Touch the leads, one each, to the capacitor's terminal connectors. Hold the leads in place to discharge the capacitor of any power. The meter may register some form of voltage value, but should soon dissipate down to zero volts. When the start capacitor has been fully discharged, switch the meter to the Ohms position on the meter's switch. Remove the red lead from the Volts connector and place it into the ohms connector. Touch the two leads to the two terminals of the capacitor. The resistance reading should begin at zero ohms and then slowly climb in the resistance-reading display. This indicates that the capacitor is storing a small electric charge from the meter. The capacitor is good. The capacitor is bad and should be replaced if: 1.If the meter immediately shows a very high resistance reading, in which case the capacitor has an open in the circuit. 2.If the meter remains at zero ohms and does not climb in the reading.
