There are several ways to find watts; volts x amps = watts or resistance (ohms) divided by amps squared or volts squared divided by amps.

You can search for Ohm's Law to find examples of these different methods and sample calculations.

How many amps equal 1800 watts at 110 volts?

To find the amperage, you can use the formula: Amps = Watts/Volts. Plugging in the values, you get Amps = 1800 Watts / 110 Volts ≈ 16.36 Amps.


Ow do you calculate amperage with watts and volts?

You can calculate amperage (A) using the formula A = W / V, where W is the power in watts and V is the voltage. Simply divide the power in watts by the voltage to find the amperage.


What is the formula for watts?

Watts is voltage (in volts) x current (in amps)


How many watts are consumed by a light bulb if 1.2 amperes are measured when 12 volts are applied?

The power consumed by the light bulb can be calculated using the formula P = I * V, where P is power in watts, I is current in amperes, and V is voltage in volts. In this case, the power consumed is 1.2 amperes * 12 volts = 14.4 watts.


Which equation should be used to find current when volts and watts is given to you?

You can use the formula I = P/V, where I is the current in amperes, P is the power in watts, and V is the voltage in volts.


What is the formula for converting mets to watts in exercise physiology?

The formula for converting METs to watts in exercise physiology is: Watts METs x 3.5 x weight in kg / 200.


If you have 72 watts and 12 volts dc how many amps am i producing?

To find the amperage, you can use the formula: Amps = Watts / Volts. In this case, with 72 Watts and 12 Volts, you would have 6 amps of current.
