Question 1

A capacitor is charged by connecting it in series with a resistor to a DC source. The greatest change in voltage across the capacitor will occur during:  


the first time-constant period.


the second time-constant period.


the fourth time-constant period.


the fifth time-constant period.



Question 2

A lamp connected in series with a capacitor and an AC voltage source will light up. This is because:  


the dielectric is shorted out automatically when alternating current is applied.


the peak AC voltage, being higher than the equivalent DC voltage, can temporarily break down the dielectric.


the lamp is also acting as a capacitor when connected in series with an actual capacitor.


the capacitor is being alternately charged and discharged, resulting in a continuous flow of current through the lamp.

A strange skin disease referred to as Morgellons has occurred in the southern United States and in California. Symptoms include slowly healing sores, joint pain, persistent fatigue, and a sensation of things crawling through the skin. Another symptom is strange-looking, threadlike extrusions coming out of the skin.

Did you know?

Dogs have been used in studies to detect various cancers in human subjects. They have been trained to sniff breath samples from humans that were collected by having them breathe into special tubes. These people included 55 lung cancer patients, 31 breast cancer patients, and 83 cancer-free patients. The dogs detected 54 of the 55 lung cancer patients as having cancer, detected 28 of the 31 breast cancer patients, and gave only three false-positive results (detecting cancer in people who didn't have it).

Did you know?

Human stomach acid is strong enough to dissolve small pieces of metal such as razor blades or staples.

Did you know?

All patients with hyperparathyroidism will develop osteoporosis. The parathyroid glands maintain blood calcium within the normal range. All patients with this disease will continue to lose calcium from their bones every day, and there is no way to prevent the development of osteoporosis as a result.
