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.

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.
