#### Amps equation

## How do I calculate volt amps?

How Are Volt-Amperes Calculated? The apparent power for dc circuits is the same as real power for dc circuits (for dc, VA = W). You can calculate the apparent power in volt-amperes for ac circuits by multiplying the measured RMS voltage times the measured RMS current.

## How can I calculate watts?

Multiply the number of amps by the number of volts to obtain the number of watts in the circuit. The equation W = A x V shows this relationship where W is the wattage, A is the amperage and V is the voltage.

## What is the formula for power?

Power equals work (J) divided by time (s). The SI unit for power is the watt (W), which equals 1 joule of work per second (J/s). Power may be measured in a unit called the horsepower. One horsepower is the amount of work a horse can do in 1 minute, which equals 745 watts of power.

## How many amps is a 120 volt?

Watts and amps conversions at 12V (DC)

Power | Current | Voltage |
---|---|---|

90 watts | 7.5 amps | 12 volts |

100 watts | 8.333 amps | 12 volts |

110 watts | 9.167 amps | 12 volts |

120 watts | 10 amps | 12 volts |

## How many amps is a 500va transformer?

5 Amp

## How many watts is 220 volts?

How many watts/volt in 1 watts/220 volts? The answer is 0.0045454545454545. Note that rounding errors may occur, so always check the results.

## What is the 5 rule in physics?

The purpose of the 5% Rule is to give you the option of eliminating a vertical axis intercept. When you have a vertical axis intercept that you believe exists only because of error in your data, the 5% Rule can be invoked (if all conditions are met) and the intercept may be dropped from you mathematical equation.

## What is average power formula?

If the resistance is much larger than the reactance of the capacitor or inductor, the average power is a dc circuit equation of P=V2/R, where V replaces the rms voltage. An ac voltmeter attached across the terminals of a 45-Hz ac generator reads 7.07 V.
