Watts cannot be calculated using the number of volts alone. Amperage is required, too.
Continue ReadingTo 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.

Full Answer >A buck-boost transformer is typically used when line voltage needs to be increased from 208 to 240 volts. The voltage increase is often used to supply adequate voltage to accommodate the load requirements of specific machines, such as heating, ventilation and air conditioning equipment
Full Answer >A 12-volt electrical system operates on 12-volt current rather than the more typical 120-125 volts located in most homes and businesses. A 12-volt electrical system is common in recreational vehicles, camping trailers, cars and trucks. Those with solar power systems often use 12-volt systems.
Full Answer >In the field of electronics, VDC stands for volts of direct current. Direct current is the type of current that comes from a battery or the power supplies of many electronic devices.
