CRAO is considered a stroke of the eye. Studies show that about two-thirds of patients have underlying high blood pressure and one-fourth of patients will have significant carotid artery disease (plaque with narrowing of the artery lining), cardiac valvular disease or diabetes.
Electrical pressure is measured in volts, or voltage. All electrical devices are rated for specific voltages. Most devices and small appliances in a home are rated for 120 volts, while high-voltage appliances, such as electric dryers, ranges, and many baseboard heaters, are rated for 240 volts.
Best Answer: Electricity is measured in volts, amps and watts. Volts measure the âpressureâ under which electricity flows. Amps measure the amount of electric current. Watts, named to honor the inventor of the steam engine, James Watt, measure the amount of work done by a certain amount of current under a certain pressure. One watt is a very small amount of power. On average, a typical household incandescent light bulb uses 40 to 100 watts.
