Appliance Watts/Amps Calculator Electricity is measured in units of energy called watts, named after James Watt, the inventor of the steam engine. Watts is generally defined as the amount of power (or energy) an appliance uses (consumes) when operated at its maximum capacity for 1 hour.Amps on the other hand is defined as how much energy an appliance draws, or the rate of energy that flows through wire when an appliance is used for 1 hour.ou can determine power characteristics of an appliance if watts rating is not provided, by the following equation: V (Volts) X A (Amps) = Watts (Ohm's Law) A=W/V V=W/A To determine Amps consumed by a 25watt 12V light bulb, for example, use the equation A=W/V or (25/12=2.1Amps).
Common causes of mouth ulcers. The most common causes of mouth ulcers are related to disturbances of the mouth and include: 1  Bacterial infections. 2  Canker sores. 3  Dietary deficiencies, such as lack of vitamin B-12, zinc, folate (folic acid), or iron. 4  Emotional stress. 5  Food allergies. 6  Nutritional deficiency. 7  Spicy foods.
1 Oral Ulcers: Usually, an ulcer is referred to as an open wound which is formed inside the mouth and this occurs due to the invasion of micro organisms. 2  Sometimes, blood blisters are caused due to the skin infections caused as a side effect of medications. 3  Ulcers are of two types they are: Canker sores and Cold sores.
