How much amperes does a 40W fluorescent lamp draw?
A 40W fluorescent lamp typically draws around 0.33 amperes in a 120V circuit. This is calculated by dividing the power (40W) by the voltage (120V) to get the amperage.
What is a reverse connected 120V ballast?
A reverse connected 120V ballast is a type of ballast that can operate a fluorescent lamp with reversed polarity. This means that it allows the lamp to be connected to the power source in reverse compared to a standard ballast, providing flexibility in certain lighting applications.
How you can calculate the ampere for fluorescent lamp with use VA?
To calculate the amperes for a fluorescent lamp using VA (volt-ampere), you can divide the VA rating by the voltage of the lamp. The formula is: Amperes = VA / Voltage. For example, if a fluorescent lamp has a VA rating of 60 VA and operates at 120 volts, the amperes would be 0.5A (60 VA / 120V).
What is more efficient a 120V 13W fluorescent bulb or a 12V 50W halogen bulb?
Fluorescents are always 3-4 times more efficient than halogens which are a version of incandescent bulb.
I have a 120V bulb and want to replace it with a compact fluorescent bulb. Is there an equivalent?
You need to look at the bulbs' light-output equivalents rather than voltages. Neither voltage nor wattage is a measure of light output; nearly all household bulbs in North America operate on 120 volts regardless of how much light they produce, and different types of bulbs produce different amounts of light despite having the same wattage rating. Both incandescent and CFL bulbs should be marked with their light output, usually in lumens. Try to pick a CFL whose light output is as close as possible to the incandescent bulb you're replacing.
What are the best 120v portable battery options for powering devices on-the-go?
Some of the best 120v portable battery options for powering devices on-the-go include the Jackery Portable Power Station, Goal Zero Yeti 150, and Anker Powerhouse. These batteries are compact, lightweight, and provide reliable power for charging various devices while you're away from a traditional power source.
How do you wire a 120v A base emter for 120v?
To wire a 120V A base emitter for 120V, you would typically connect the emitter to the ground, the base to the input voltage source (120V), and the collector to the load. Ensure you follow proper safety precautions and consult the specific datasheet for the A base emitter you are using for correct wiring instructions.
What are the features and specifications of the portable power bank 120v?
The portable power bank 120v is a device that can charge electronic devices on the go. It has a capacity of 120 volts and typically includes multiple USB ports for charging various devices simultaneously. It is compact and lightweight, making it easy to carry around. Some models may also have additional features such as LED indicators to show the remaining battery level.
What is the calculated load in amps for a 120V circuit supplying four 150W recessed incandescent fixtures and six recessed fluorescent fixtures operating continuously?
To calculate the load in amps for the circuit, first determine the total wattage of the fixtures. The four 150W incandescent fixtures contribute 600W (4 x 150W), and the six fluorescent fixtures (assuming a typical wattage of 32W each) contribute 192W (6 x 32W). Adding these together gives a total of 792W. Using the formula ( \text{Amps} = \frac{\text{Watts}}{\text{Volts}} ), the load in amps is ( \frac{792W}{120V} = 6.6A ).
1000 watt generator power can it power a compact fridge?
yes, it has an output of 20 amps @ 120v so it will power any standard refrigerator. I believe a 900 Watt Generator will only handle 7.5 amps at 120 Volts.
37.5 amps converted in watts?
To convert amps to watts, you also need the voltage. The formula to calculate power in watts is Watts = Amps x Volts. If the voltage is 120V, then 37.5A would be equivalent to 4500W (37.5A x 120V = 4500W).
