Power in watts equals amperes times voltage. So, in a direct current, 1 amp at 110 volts equals 110 watts, whereas 1 amp at 220 volts equals 220 watts.Continue Reading
Amp wattage depends on the voltage and on whether it is a direct current or an alternating current. The same appliance can consume more or less watts if it is plugged into a 110-volt current or a 220-volt current. By rule, 220 volts consumes more watts.
In an alternating current, the power factor must also be taken into consideration. The power factor indicates the ratio between real power and apparent power in a circuit.Learn more about Measurements
The only difference between an amp and a milliamp is that an amp is 1,000 times larger than a milliamp. Both amps and milliamps are metric units used by scientists to measure electrical current, although at different scales.Full Answer >
One amp is equivalent to 1,000 milliamps, commonly denoted by the symbol mA. Amperage measures the amount of current flow in an electrical circuit in units of amperes, or amps.Full Answer >
Because these two terms measure two different aspects of electricity, it is not possible to convert between the two. Amperage is a measure of current flow past a given point, while voltage is the potential for current flow.Full Answer >
At 115 volts of current, 115 watts is equal to one amp, but the number of watts to equal an amp varies based on the current. If using a 12-volt battery to power the circuit, 12 watts is equal to one amp.Full Answer >
