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.
An hour is just 3600 seconds so a Watt hour is simply 1 Watt (Or 1 Joule per second) for 3600 seconds which equals 3600 Joules. 1 kWh is 3600,000 joules and 1 kW is 1000 joules per second. Now that's out of the way, we basically have three different ways of measuring energy usage per person.1.The energy they produce in their muscles. 2.o find out how much energy you use directly in appliances, it's probably easiest just to watch what you do each day and write it down. Add up your energy usage for your house on your electricity meter for a month (usually in kWh) and divide it by the number of days in the month and the number of people in the house.
