BROVANA Â® (arformoterol tartrate) Inhalation Solution is a long-acting beta 2-adrenergic agonist (LABA) indicated for the long-term, twice-daily (morning and evening) maintenance treatment of bronchoconstriction in patients with chronic obstructive pulmonary disease (COPD), including chronic bronchitis and/or emphysema.
The oil drop experiment was performed by Robert A. Millikan and Harvey Fletcher in 1909 to measure the elementary electric charge (the charge of the electron). The experiment entailed observing tiny electrically charged droplets of oil located between two parallel metal surfaces, forming the plates of a capacitor.
14 Sep 07 Millikan.1. MILLIKAN OIL DROP EXPERIMENT. This experiment is designed to show the quantization of electric charge and allow. determination of the elementary charge, e. As in Millikanâs original experiment, oil drops are sprayed into a region where a uniform. electric field can be established, and the motions of drops are studied under the action of the. electric field being turned on and off. Although this experiment will allow one to measure the total charge on a drop, it is only.
