To figure out how many amps are needed, divide the number of watts by the voltage. For example, a 120-watt device, requiring 1,200 volts requires 10 amps. This is the full article.
How do I calculate amps from watts?
The formula for converting amps to watts (at a fixed voltage) is watts = amps × volts.
How many volts are in an amp?
At 120V, 120 watts make 1 amp. So, 1 amp is equal to 120 watts. This is the full article.

What is the formula for calculating load?
Multiply the mass of the object by the gravitational acceleration of the earth (9.8 m/sec2), and the height in meters. This equation is the object at rest’s potential energy. Potential energy is measured in joules; this is the load force.

How do you convert volts to amps? The formula to convert volts to amps at a fixed wattage is: amps = watts / volts.
How do you calculate amps in a 3 phase circuit?
Divide the power consumption in watts by the line voltage multiplied by the power factor to find the amperage. For three phase circuits the power factor is the square root of 3. If your calculator doesn’t have a square root function, use 1.73 as an approximation of the square root of 3.

What is a 20 amp circuit?
The 20-Amp Circuit
A typical circuit of 20 amperes (amp) is enough to power a bedroom or two. It is a common amp rating used in devices such as outlets and overhead lights, along with a 15-amp circuit. Different amps suit different wire sizes.
How do I calculate 240v amps?
Divide the number of watts by the voltage to calculate the amperage for a single-phase circuit. Since this is a 240-volt device, you would divide the watts by 240 volts. For example, a 1,800-watt device would use 7.5 amps. Divide this figure by 1.732 to calculate the amps for a three-phase circuit.
What is difference between amps and voltage?
Voltage and amperage are two measures of electrical current or flow of electrons. Voltage is a measure of the pressure that allows electrons to flow, while amperage is a measure of the volume of electrons.
