Watts cannot be calculated using the number of volts alone. Amperage is required, too.Know More
To find how many watts are in 120 volts, one need to know the formula that relates power (P) in watts to volts (V) and current (I) given in amps. The formula for this relationship is that power equals volts multiplied by amps, or P = V x I.
So, if the question is how many watts are in 120 volts that delivers a current of 2 amps, then the answer is 240 watts using the formula.
Watts, amps, volts and ohms are the units utilized to measure electricity.Learn more about Electrical
Connected to standard 120-volt service, a 15-amp circuit would allow approximately 1800 watts of power before becoming overloaded. For long-term loads, including anything that draws current for more than three hours, the maximum wattage allowed would be 20 percent lower, at 1440 watts.Full Answer >
A 15-amp fuse can handle no more than 1,800 watts of power. Anything over that will cause the breaker to trip.Full Answer >
To convert a 220-volt outlet to a 110-volt outlet, either purchase an adapter or remove the existing receptacle from the outlet box. Either option allows a 110-volt appliance to plug into a previously 220-volt outlet.Full Answer >
Typical outlets in U.S. homes and businesses have a rating of 120 volts. Specialty outlets for larger items such as a stove, electric clothes dryer or a large-BTU air conditioner carry more voltage, but the vast majority of the wall outlets have two-prong outlets with a third hole for grounding.Full Answer >
