What is the output of a light ballast?

Fluorescent electronic ballasts have a voltage to amperage ratio chart on their face. Use this chart by selecting the voltage you are using and the corresponding amperage, then multiply the two numbers together for your wattage. Some fixtures come with more than one ballast, so you will need to take the wattage of all applicable ballasts for any given fixture to obtain the total wattage for the fixture.


What is the calculated wattage of a computer that draws 4 A of current?

To calculate the wattage of a device, you need to know both the current (in amperes) and the voltage (in volts). If the voltage is not provided, you cannot accurately calculate the wattage. In this case, with only the current (4 A) given, you cannot determine the wattage without knowing the voltage as well.


What is breaker size for 62.19 KW 3 phase?

A breaker protects the wire size of the feeder that is connected to it. The amperage of the load must be found. Without a voltage stated the amperage from the wattage given can not be calculated. The equation for amperage when the kw is given is A = kW x 1000/1.73 x volts x pf. The pf constant to use is .9.


How many amps do you need to power 1hp?

The amperage of a motor is governed by the voltage that the motor operates on. Without a voltage given, an answer can not be given.


What is the voltage loss over 400 feet?

To answer this question the supply voltage and the amperage of the load must be given.


How many amps are in three ohms?

NONE! By itself this is a meaningless question. Doubt it? pick up a 3 ohm resister and see if you get anything in amperage out of it . add some voltage to it and you will get some amperage, depending on the amount of voltage. Of course add to much voltage and you will burn the resistor up, depending on its wattage rating


How many amps is 3000 watts?

To calculate the amperage for a given wattage, you would also need the voltage of the circuit. However, if we assume standard 120V household voltage, then 3000 watts would be equivalent to 25 amps (3000 watts / 120 volts = 25 amps).


How do you determine the amperage given the voltage and power dissipated?

Like Ohm's Law, the formula for calculating power is a simple product of two quantities. It is given by the formula P = VI, where V is the voltage in volts and I is the current in amperes (or simply amps). So, if you know the value of any two of the quantities, you can easily calculate the third with simple arithmetic. For example, if the current flowing through a resistor is two amps and the voltage drop across that resistor is five volts, the power dissipated by the resistor is, P = VI = 5 volts * 2 amps = 10 watts. If you are given the power and the voltage, you can easily find the current. For example, if you are told that the voltage drop across a resistor is five volts and is dissipating 10 watts, the current through the resistor is 10 watts/5 volts = 2 amps.


How many watts is in 9 volts?

You can't convert volts to amperes. Those are quite different units; that would be like converting, say, meters to seconds.

How do you determine if the Primary voltage is unknown but Secondary voltage is given?

If a secondary voltage is given across a particular resistive load in a series of known resistive loads, multiply the voltage by the ratio of the total load to the measures load to get total voltage. Example: You have a series of a 200 ohm resistor to a 100 ohm resistor. The votage measured across the 100 ohm is 2 volts. 200 + 100 = 300. 300 / 100 = 3. 2 X 3 = 6. Total Voltage in the circuit is 6V


How many amps is 9000 watts?

To determine the amperage for 9000 watts, you need to know the voltage at which the power is being consumed. The formula to calculate amperage is Amps = Watts / Volts. For example, if the voltage is 120V (typical for household circuits in the US), the amperage would be 9000 watts / 120 volts = 75 amps. However, if the voltage is different, such as 240V, then the amperage would be 9000 watts / 240 volts = 37.5 amps.
