What gauge wire for a jacuzzi with a 40 foot run?
Depends on the amperage of the Jacuzzi and if it is 120 or 240 volts.
What does 40 VA mean in a transformer?
In a transformer, 40 VA refers to the apparent power rating of the transformer. VA stands for volt-ampere, which is a unit used to measure apparent power in an electrical circuit. A transformer with a rating of 40 VA can handle a maximum apparent power of 40 volt-amperes, which is the product of the voltage and current it can handle. This rating is important for determining the capacity and suitability of the transformer for specific applications.
Can you connect a 220 volt stove to a 120 volt circuit?
Yes, this is a safe connection. A range is usually wire rated at 40 amps and the manufactures do not make a 40 amp rated receptacle. The code requires the next highest rated receptacle be used which is a 50 amp rating. This is why the range receptacle is rated at 50 amps. This receptacle is known as a 3 pole 4 wire grounding receptacle, 14-50R 125/250 volt. Black wire to terminal X, red wire to terminal Y, white wire to terminal W and ground wire to terminal G.
How many amps are in 40 volt amps?
Multiply the vots by the amps to find the volt-amps. Or divide the volt-amps by the voltage to find the amps.
How many take amp 40 watt fluorescent lamp?
Watts= voltage times amps. So if you divide Watts by voltage, you will get amps = .33333 or about a 1/3 amp load. This is assuming a 120 volt circuit.
How many amps are in 40 watts?
That depends on circuit voltage. 1 watt is equal to 1 volt times 1 amp.
How many watts make a volt?
Watts are a unit of power and Volts are a unit of electric potential, so they cannot be directly compared. However, Watts and Volts can be related byWatts = Volts * AmperesorWatts = (Volts^2) / Ohmswhere Amperes are a unit of current and Ohms are a unit of resistance. So, for example, if a lightbulb draws .333 Amps of current at 120 Volts, it is a 40 Watt bulb. (.333 A * 120 V = 40 W)
What is the resistance of a 40 watt bulb?
On this calculation I am assuming that the light bulb is using a 120 volt source. Watts = Amps x Volts. Amps = Watts/Volts, 40/120 = .33 amps. R = Volts/Amps, 120/.33 = 363.6 ohms resistance in the 40 watt light bulb.
How many watts in 40 amps?
I t depends. Watts = Amps times volts. 40 amps x 120 volts =4800 watts or 40 Amps x 12 volts = 480 watts.
What is LM 105?
LM105 series are monolithic voltage regulators, basically about 4.5 volts output, but which can be configured to deliver up to 40 volts.
How do you work out how many amps a forty watt bulb uses?
To calculate the amperage of a 40-watt bulb, you need to use the formula: Amps = Watts / Volts. If the bulb operates at 120 volts (standard for US households), the amperage will be 0.33 amps (40 watts / 120 volts).
Can you connect a 12 volt auto alternator to a 24 volt system to charge the batteries?
If you connect an alternator that has been designed for charging a 12 volt battery to any 24 volt system in an attempt to charge its batteries, that alternator will not work because of either of two different reasons:if the 24 volt battery is completely dead or flat the 12 volt alternator will not be able to charge it to much above 18 volts. That is about as much practical use as having a flat 24 volt battery!if the 24 volt battery is not "flat" but has a voltage that is in its normal range - between about 23 volts and 27 volts - the 12 volt alternator would not do anything because its output voltage cannot go high enough.Some more facts:12 volt systemsAn alternator designed to charge a nominal 24 volt battery will have a voltage and current regulation system to control its output voltage between about 13.5 and 18 volts and an output current that could vary between zero and about 40 or 50 amps.The overall range of current amperage output from the alternator would vary from vehicle to vehicle depending on the sizes of the alternator and battery and those in turn would be sized to match the likely normal current amperages drawn by the vehicle's ignition, night-time road lighting, air conditioning and other systems.The actual charging voltage and current being output from the alternator at any instant depends on the "state of charge" of the 12 volt car battery. A nominal 12 volt lead-acid type car battery that is flat has a voltage of about 11.5 volts or less. One that is fully charged would have a voltage of about 13.5 volts.24 volt systemsAn alternator designed to charge a nominal 24 volt battery will have a voltage and current regulation system to control its output voltage between about 27 and 36 volts and an output current that could vary between zero and about maybe 80 or 100 amps.The overall range of current amperage output from the alternator would vary from vehicle to vehicle depending on the sizes of its alternator and battery and those in turn would be sized to match the likely normal current amperages drawn by the vehicle's ignition, night-time road lighting, air conditioning and other systems.The actual charging voltage and current being output from the alternator at any instant depends on the "state of charge" of the 24 volt vehicle battery. A nominal 24 volt lead-acid type battery that is flat has a voltage of about 23 volts or less. One that is fully charged would have a voltage of about 27 volts.Only in the instance where two 12 volt batteries were connected in series to produce power for a 24 volt system, could a method be devised to use a 12 volt alternator to charge the batteries independently.
What gauge wire for a jacuzzi with a 40 foot run?
Depends on the amperage of the Jacuzzi and if it is 120 or 240 volts.
A transformer has 520 turns in its secondary coil and a secondary output voltage of 480 volts The primary coil has 40 turns What is the primary voltage?
36.9 volts Explanation: A trafo works in ratios, much the same as percentage. Easily calculated in this question . 520 turns and 480 Volts secondary. We find the Voltage of each turn by dividing Voltage by turns. 480/520=0,9230769231 Volt. Then multiply this by primary turns of which is 40. 40*0,9230769231 =36,9230769231 Volts. More related info: This is the AC voltage. In order to find a quite accurate estimate for a rectified DC output with a charging capacitor, simply multiply the AC voltage by 1.44
A 120 ohm resistor a 60 ohm resistor and a 40 ohm resistor are connected in parallel to a 120 volt power source. What is the current running through the 120 ohm resistor?
1amp
60 ohm and 40 ohm and 20 ohm resistors are all 3 connected in series across a 120VAC source what is the total voltage across 40 ohms resistance?
Total resistance is 120 ohms. The 120VAC will be split evenly over this 120 ohm load, so every ohm of resistance gets a volt. So there will be a 40 volt drop across the 40 ohm resistor.
What wattage of inverter would you need to power a 100-240volt 1.7 amp laptop?
At 100 volts, around 170 watts. At 240 volts, around half as much. So, I'd suggest a nice 200 watt inverter for the 120 volt model, but that seems to be an awful lot for your purposes. Are you sure that you're not reading the power output of the power adapter, as compared to the amperage it draws on A.C.? I seem to remember using my laptop in a truck with just a 40 watt inverter and it worked just fine.
